In this talk\, we will discuss the development of functional micro/nanostructures\, based on laser-processed surfaces. \nCoating micro/nanostructures with thin metallic films results in plasmonic substrates with enhanced electromagnetic response across the entire visible range\, which are used for plasmonic optical trapping [1]. Combining silicon micro/nanostructures with thin semiconducting films results in electronic heterojunctions with increased surface area for improved optoelectronic performance [2]. Furthermore\, isotype heterojunctions result in wavelength-selective\, high-speed photodetectors with self-powered operation\, which can be further engineered by careful selection of the electronic properties of the constituting materials [3\,4]. “Smart” surfaces of controllable extreme wetting states are obtained by combining photoresponsive metal oxides with laser-processed micro/nanostructured substrates\, which can reach complete water repellence without chemical modification [5]. Also\, surfaces with controlled topography\, either at the micro- or at the nano-scale\, for targeted cell cultures for biomedical applications [6]. We will present recent advances in these fields and discuss future applications. \nReferences \n\n \nD.G. Kotsifaki\, M. Kandyla\, and P.G.

The experiments concern formation of astrophysical jets\, photoionized plasmas in accretion disks around compact stars\, supernovae explosions\, matter formed inside giant planets\, formation of interstellar dust\, molecular processes in interstellar ices\, formation of tholins etc. It is so called laboratory astrophysics or astrochemistry. \nSome of these experiments require using of high power discharge or laser systems\, for some experiments\, especially concerning laboratory astrochemistry\, synchrotrons\, VUV lamps or small scale discharge plasma systems were employed. Some experiments can be\, however\, performed using laser produced plasma (LPP) soft X-ray (SXR) or extreme ultraviolet (EUV) sources. Some attempts were performed using sources developed in Institute of Optoelectronics\, MUT. \nThe sources utilize gas puff targets and nanosecond\, Nd:YAG laser systems. The most intense emission in the SXR or EUV range can be obtained from Xe plasmas\, however\, in some cases other gases or aerosols are employed. The sources are equipped with the corresponding EUV/SXR optical systems. Some experiments are performed in an ambient gas\, under low pressure. Both kind of systems\, with and without optics\, can be employed for investigation of molecular processes relevant to SXR/EUV induced processes in interstellar clouds\, atmospheres of planets or comets. Initial experiments were performed\, a series of further experiments is planned. \n \n \n \n \n \n \n \n \n \n \n \n \n \n Watch this Talk URL:https://lasers4.eu/event/lle-talk-laser-produced-plasmas-lpp-sxr-euv-sources-for-laboratory-astrochemistry/ CATEGORIES:Webinars ATTACH;FMTTYPE=image/png:https://lasers4.eu/wp-content/uploads/lle-talk_thumbnail_bartnik.png END:VEVENT BEGIN:VEVENT DTSTART;TZID=Europe/Berlin:20260113T103000 DTEND;TZID=Europe/Berlin:20260113T120000 DTSTAMP:20260430T160759 CREATED:20251113T000245Z LAST-MODIFIED:20251113T000656Z UID:6506-1768300200-1768305600@lasers4.eu SUMMARY:Lasers4EU Activity Board meeting\, 13 January 2026 DESCRIPTION:The Activity Board of the Lasers4EU project will hold its next meeting on 13 January from 10:30 to 12:00 CET. \nLogin details will be provided by the Laserlab-Europe Office. \nPlease note: this is an internal project event.

These techniques are based on the PA effect\, which involves the generation of acoustic waves as a result of the absorption of intensity-variable optical radiation. The excitation and detection of PA signals through spectroscopic or imaging modalities is non-invasive and non-destructive and provides high optical absorption sensitivity at substantial depths within opaque media\, surpassing the performance of several purely optical diagnostic methods. \nIn this context\, we present a novel reflection-mode PA system integrating near-infrared pulsed excitation light and a spherically focused air-coupled ultrasonic transducer for the detection of the generated PA waves. The system is specifically developed to detect in-depth ageing effects in painted mock-ups and to reveal hidden underdrawings\, such as pencil sketches\, beneath non-transparent paint layers. To assess the performance of the system in detecting degradation phenomena\, PA responses were recorded from different pigmented layers that had undergone controlled thermal or photo-ageing treatments. The measurements revealed a progressive increase in the PA amplitude over time\, with distinct deterioration rates observed for various types of paint. \nAdditionally\, by employing a second-harmonic excitation wavelength at 532 nm and comparing the PA signal ratios obtained from the two excitation lines\, we aimed to enhance the method’s detection sensitivity while also expanding its applicability. Beyond the investigation of ageing effects in painted mock-ups\, the developed dual-wavelength PA approach enabled the identification of corrosion levels in various metals and alloys\, differentiation among inks of similar visual appearance\, and detection of degradation effects in artificially aged papers. Overall\, these results highlight the strong potential of PA detection as a complementary diagnostic technique to traditional methods\, offering highly sensitive and non-destructive insights into degradation mechanisms and subsurface features across a broad range of CH artifacts. \n \n Watch the Laserlab-Europe Talk URL:https://lasers4.eu/event/lle-talk-non-invasive-photoacoustic-imaging-for-in-depth-cultural-heritage-diagnostics/ CATEGORIES:Webinars ATTACH;FMTTYPE=image/png:https://lasers4.eu/wp-content/uploads/Thumbnail_eleanna.png END:VEVENT BEGIN:VEVENT DTSTART;TZID=Europe/Berlin:20251126T160000 DTEND;TZID=Europe/Berlin:20251126T170000 DTSTAMP:20260430T160759 CREATED:20251112T151646Z LAST-MODIFIED:20251127T120645Z UID:6500-1764172800-1764176400@lasers4.eu SUMMARY:Laserlab-Europe Talk: Nonlinear optical diode effect in a magnetic Weyl semimetal\, 26 Nov 2025 DESCRIPTION:Speaker: Christian Tzschaschel (University of Zurich) \nWeyl semimetals have emerged as a promising quantum material system to discover novel electrical and optical phenomena\, due to their combination of nontrivial quantum geometry and strong symmetry breaking. Here\, I will present the observation of the nonlinear optical diode effect (NODE) in the magnetic Weyl semimetal CeAlSi\, where the magnetic state of CeAlSi introduces a pronounced directionality in the nonlinear optical second-harmonic generation (SHG). By physically reversing the beam path\, we show that the measured SHG intensity can change by at least a factor of six between forward and backward propagation over a wide bandwidth exceeding 250 meV. Supported by density-functional theory calculations\, we establish the linearly dispersive bands emerging from Weyl nodes as the origin of the extreme bandwidth. By utilizing the electronically conductive semimetallic nature of CeAlSi\, we demonstrate current-induced magnetization switching and thus electrical control of the NODE in a mesoscopic spintronic device structure. Our results advance ongoing research to identify novel nonlinear optical/transport phenomena in magnetic topological materials. The NODE further opens new pathways for the unidirectional manipulation of light such as electrically controlled optical isolators [1]. \n[1] CT et al.\, Nature Communications 15\, 3017 (2024) \n \n Watch the Talk URL:https://lasers4.eu/event/laserlab-europe-talk-nonlinear-optical-diode-effect-in-a-magnetic-weyl-semimetal-26-nov-2025/ CATEGORIES:Webinars ATTACH;FMTTYPE=image/png:https://lasers4.eu/wp-content/uploads/Thumbnail_tzschaschel.png END:VEVENT BEGIN:VEVENT DTSTART;TZID=Europe/Berlin:20251117T100000 DTEND;TZID=Europe/Berlin:20251117T113000 DTSTAMP:20260430T160759 CREATED:20251113T000925Z LAST-MODIFIED:20251113T065604Z UID:6512-1763373600-1763379000@lasers4.eu SUMMARY:Lasers4EU Industrial Advisory Committee meeting\, 17 November 2025 DESCRIPTION:The first meeting of the Lasers4EU Industrial Advisory Committee (IAC) will take place on 17 November 2025\, bringing together representatives from industry and project partners to help guide the project’s strategic direction. \nIAC members are expected to provide professional and technical input on key aspects of the project\, including exploitation opportunities\, innovation needs\, and the incorporation of industry perspectives into the design and evaluation of project activities.

Lasers4EU partners are warmly invited to join the online sessions. \nA session of particular relevance for the Lasers4EU community will address data management planning using RDMO (Research Data Management Organiser). As funding agencies increasingly require Data Management Plans (DMPs) defining how data and metadata are handled during and after projects\, the HZDR instance of RDMO\, accessible via Helmholtz ID\, supports collaborative preparation of DMPs\, even with external partners. \nWithin this context\, the Lasers4EU project serves as a potential use case for tailoring generic DMP questionnaires to specific needs\, distinguishing between questions for proposing scientists\, access-providing facilities\, and repository providers. The session will therefore be of direct interest to Lasers4EU partners involved in data management\, access coordination\, and research infrastructure development. \nFor more information and the full programme\, please visit HZDR Data Management Days 2025 \n \n Register here URL:https://lasers4.eu/event/hzdr-data-management-days-2025/ CATEGORIES:Project,Webinars ATTACH;FMTTYPE=image/png:https://lasers4.eu/wp-content/uploads/2024/08/Logo_Lasers4EU-2024_rgb.png END:VEVENT BEGIN:VEVENT DTSTART;VALUE=DATE:20251104 DTEND;VALUE=DATE:20251108 DTSTAMP:20260430T160759 CREATED:20250626T102204Z LAST-MODIFIED:20250721T103120Z UID:5193-1762214400-1762559999@lasers4.eu SUMMARY:Lasers4EU Training: Hands-on Course on MINDLAB: Manipulating and Investigating Neural Dynamics for Learning and Ageing in the Brain\, 4-7 Nov 2025 DESCRIPTION:The core faculty of the ICFO-MINDLAB\, a think tank working jointly towards a transdisciplinary understanding of the brain\, offers a school to introduce cutting edge technologies to study neuroscience at the molecular\, cellular and systems level to students in a combination of lectures and hands-on experience leading to group projects. \nWhat is MINDLAB?\nMINDLAB stands for “Manipulating and Investigating Neural Dynamics for Learning and Ageing in the Brain” and is an interdisciplinary creative playground rooted squarely in academic rigor\, comprising of research groups from ICFO and beyond.

In the case of terawatt and petawatt lasers\, the intensity of the EMP is strong enough to interfere with diagnostic signals and may cause malfunction or distortion of electronic devices. Moreover\, the laser-driven EMP could cause problems in experimental basic research\, inertial nuclear fusion\, laser-plasma biomedicine and other high-power laser technologies. On the other hand\, the mechanisms of this phenomenon are not fully understood\, making it an interesting topic for the fundamental physics of laser-matter interaction. Therefore\, the laser-driven EMP is intensively studied at the PALS laser facility – a joint research infrastructure of the Institute of Plasma Physics and the Institute of Physics of the Czech Academy of Sciences in cooperation with other world-leading institutions such as the Univ. of Bordeaux\, CLF Rutherford Appleton Laboratory\, CLPU Salamanca\, ENEA C.R. Frascati\, and others. \nIn recent years we have achieved some interesting results\, such as \n\nthe observation of unprecedentedly broad EMP bandwidths;\nthe dependence of the EMP spectrum shape and upper cut-off frequency on the laser beam energy/power\, target material and target ground impedance;\nthe relation between EMP emission and the escaped electron energy spectrum;\nthe influence of the wave plate on the emission of charged particles and EMP; and\nthe characterization of the EMP caused by laser interaction with various gas targets.\n\nAs part of this research\, a number of EMP diagnostics have been developed\, such as inductive target current probes\, high-voltage target probes and B-dot arrays\, and electro-optical probes have been tested. We believe that this research will contribute to EMP mitigation\, will enrich fundamental physics knowledge\, and will also lead to numerous high-tech applications\, such as electromagnetic compatibility hardening\, biology and defense. \n \n Watch LLE Talk URL:https://lasers4.eu/event/laserlab-europe-talk-electromagnetic-pulse-generation-by-sub-nanosecond-kilojoule-laser-pulses-8-oct-2025/ CATEGORIES:Webinars ATTACH;FMTTYPE=image/png:https://lasers4.eu/wp-content/uploads/Thumbnail_yt.png END:VEVENT BEGIN:VEVENT DTSTART;TZID=Europe/Berlin:20250924T160000 DTEND;TZID=Europe/Berlin:20250924T170000 DTSTAMP:20260430T160759 CREATED:20250626T102608Z LAST-MODIFIED:20250926T133440Z UID:5200-1758729600-1758733200@lasers4.eu SUMMARY:Lasers4EU Webinar: Open science and the societal impact of scientific research\, 24 Sept 2025 DESCRIPTION:The presentation explores the principles and practices of Open Science\, highlighting how increased transparency\, accessibility and collaboration in research can enhance its societal relevance and impact.

The use of high-power pulsed laser interaction (HP PLI) offers a perspective in this field. This concept is based on laser ablation. The high-power HiLASE beamline facility (Dolní Břežany\, Czech Republic)\, with Perla-B and BIVOJ\, is used as a laser facility enabling high-energy\, short-pulse\, repetitive irradiation. First\, the performance of laser ablation propulsion (LAP) will be presented by measuring the coupling coefficient (Cm) using a specially designed ballistic pendulum coupled with a Photonic Doppler Velocimetry system and an angle measurement using laser deflection. Second\, to illustrate such an application\, a “V-track” system will be introduced with the quantification of the laser/matter interaction-induced velocity of ablated targets. Model materials are used (metal and polymers). The laser conditions are suitable for the prospect of laser propulsion with limited creation of additional debris. \n \n \n \n \n \n \n \n \n \n \n \n \n \n Watch the Laserlab-Europe Talk URL:https://lasers4.eu/event/lle-talk-laser-ablation-propulsion/ CATEGORIES:Webinars ATTACH;FMTTYPE=image/png:https://lasers4.eu/wp-content/uploads/Thumbnail_boyer.png END:VEVENT BEGIN:VEVENT DTSTART;TZID=Europe/Berlin:20250904T100000 DTEND;TZID=Europe/Berlin:20250904T163000 DTSTAMP:20260430T160759 CREATED:20250709T152440Z LAST-MODIFIED:20250711T121527Z UID:5406-1756980000-1757003400@lasers4.eu SUMMARY:Lasers4EU General Assembly 2025\, 4 September 2025 DESCRIPTION:One year in\, and the Lasers4EU community has already laid strong foundations.

Participants will gain insights into how these advanced photonic techniques enable precise material characterization\, real-time monitoring\, and efficient resource management—key drivers for circular economy solutions. Through expert talks\, hands-on sessions\, and interactive discussions\, the workshop will highlight the versatility and impact of these technologies across research and industry. \nThe program will also feature a poster session\, providing a platform for researchers and students to present their work\, exchange ideas\, and foster new collaborations. \nTwo hands-on sessions will offer participants practical experience in: \n\nHyperspectral Imaging – exploring its powerful capabilities in material analysis and diagnostics.\nLaser Spectroscopy – delving into its versatile applications in environmental monitoring\, quality control\, and material characterization.\n\n \n Apply until 31 May 2025\n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \nWho should attend\n\n\n\nThis workshop is designed for a diverse audience of researchers\, professionals\, and students who are interested in the intersection of photonic technologies and sustainable innovation. It will be particularly valuable for: \n\nResearchers and Academics working in material science\, photonics\, environmental science\, chemistry\, and related fields who want to explore advanced diagnostic tools and sustainable applications.\nIndustry Professionals from sectors such as recycling\, manufacturing\, environmental monitoring\, and quality control seeking innovative solutions for material analysis and circular economy practices.\nGraduate and PhD Students aiming to expand their knowledge and hands-on experience in hyperspectral imaging and laser spectroscopy.\n\nWhether you are driven by scientific curiosity\, industrial innovation\, or sustainability goals\, this workshop offers valuable insights\, networking opportunities\, and practical skills tailored to your interests. \n\n\n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n\nHands-on sessions\n\n\nHyperspectral Imaging\nUnlike traditional RGB imaging\, which captures only three spectral bands\, hyperspectral imaging (HSI) collects the entire spectrum from every point in the field of view\, producing the “spectral cube”: a stack of images taken at a large number of wavelengths. HSI synergistically combines the spatial correlations typical of imaging with the chemometric information provided by spectra\, thus enabling the identification of materials in an inhomogeneous sample. This technology has been widely used since the 1970s in several fields such as remote sensing\, medical imaging\, astronomy\, agriculture\, and conservation science\, and can now become a key technology for sorting materials in the circular economy. \nLaser Spectroscopy\nThis hands-on experimental demonstration will provide participants with a practical understanding of how to use laser spectroscopy techniques for the analysis and characterization of surfaces and materials. The following techniques will be demonstrated: \n\nLIBS: Laser Induced Breakdown Spectroscopy enables the determination of the elemental composition of materials on the basis of the characteristic atomic emission from a micro-plasma produced by focusing a high-power laser on\, a solid surface. It is widely used in various analytical applications for qualitative\, semi-quantitative\, and quantitative material analysis. LIBS is a rapid\, micro-destructive technique that can be performed both at close range and remotely (from distances of up to hundreds of meters). It can be used for bulk analysis\, depth profiling (elemental distribution with depth)\, and 2D and 3D chemical mapping.\nRaman: Raman spectroscopy is a well-established analytical technique that probes vibrational and other low-frequency modes in molecules and materials. As a result\, it provides an accurate look into chemical bonding\, thereby enabling identification of various types of materials\, both inorganic and organic. Raman spectroscopy features high sensitivity and specificity\, it is rapid\, non-destructive\, and can be performed in situ. When performed using a Raman microscope\, it offers superb spatial resolution and minimal analysis time.\n\nFollowing a brief introduction to the fundamental principles and instrumentation of both techniques\, participants will have the opportunity to use a Raman microscope and a micro-LIBS instrument (developed at IESL-FORTH) to analyse various materials. Participants are encouraged to contact us in advance if they wish to bring their own samples for potential analysis during the demonstration. \n \n \n \n \n \n \n\nThe workshop is organised within the frame of project ReMade@ARI (REcyclable MAterials DEvelopement at Analytical Research Infrastructures) co-funded by the European Union as part of Horizon Europe (GA No 10105841). \nThe event is endorsed by Laserlab-Europe through EU’s Horizon Europe co-funded project Lasers4EU (GA No 101131771).

In this contribution\, I will first give an introduction to femtosecond laser GHz-burst processing. Then\, I will show some results on glass drilling including pump-probe shadowgraphy with a temporally shaped femtosecond laser beam operating in the GHz-burst regime [4]. The pump laser source is a 100-W average power industrial femtosecond laser system emitting at a wavelength of 1030 nm that can be operated in the single pulse\, in MHz-burst and in GHz-burst regime. Pump-probe imaging in the burst regime in far from being trivial. Indeed\, a second laser is needed operating in single pulse regime for the probe beam. In order to perfectly synchronize the probe beam with the pump beam\, a portion of the pump oscillator was injected into a Yuja-based amplifier from Amplitude. Thanks to this setup\, we were able to measure the luminescence time of the plume in both burst regimes and to compare it to the regime of standard repetitive single pulses. Moreover\, we monitored the plume behavior during the drilling process of through holes revealing interesting information about the drilling process dynamics\, its limits and solutions to overcome them. \nReferences \n\nC.

One option is to chemically modify and functionalize 2D materials. However\, many applications require spatially selective functionalization and patterning. Laser-based methods offer many advantages in this regard. A common optical material modification technique is laser ablation. However\, for graphene\, more interesting condition is just below the ablation threshold\, where non-linear excitation of material takes place. Under these conditions\, graphene reacts with adsorbed oxygen and water present in ambient air\, leading to oxidative functionalization without breaking the carbon lattice integrity [1]. Interestingly\, optically induced local functionalization of graphene leads to many opportunities for development of applications via processes such as: modification of electronic properties [1]\, locally selective immobilization of proteins [2\,3]\, area-selective atomic or molecular layer deposition [4\,5]\, modification of optical properties [6]\, tuning of the response of sensors [7]\, or affecting molecular self-assembly [8]. The methods can be applied for development of sensors\, (opto)electronic devices\, flexible and transparent electronics\, bioelectronics\, and so on. \nIn this talk\, I will introduce controlled oxidative functionalization of graphene by femtosecond laser excitation and show several examples of how this method can be used to facilitate development of functional devices. \nReferences[1] J.

Modern biomedical engineering advanced the concept of “reverse engineering”\, which means building micro- and nano-structures with functional biomimicry by extracting design parameters from biological systems\, such as from cell types and shapes\, and from the complex 3D architectures of extracellular matrix microenvironments. Cells seeded on these 3D micro/nano-structures attach\, interconnect\, proliferate\, and finally form masses of cells organized in 3D architectures closely resembling the natural tissue. These micro/nano-structures are currently used not only for fundamental mechanistic studies on the development\, regeneration\, and repair of damaged human tissues\, but also for diagnostics\, disease modeling\, drug delivery\, and personalized medicine. \nIn this talk\, I will present our recent results on the fusion between reverse engineering and laser processing\, within the scope of current challenges in medical treatments. Specifically\, I will show how we “boosted” a conventional 3D printing technique\, known as Laser Direct Writing via Two-Photon Polymerization (LDW via TPP)\, for biomedical engineering. LDW via TPP has been extensively used for fabricating structures with complex 3D architectures\, for biomedical use. It is known that LDW via TPP offers low operational costs\, rapid processing time\, high spatial resolution\, and full reproducibility of the obtained structures\, mandatory for systematic in vitro studies. In our work\, we targeted the development of innovative\, synergistic combinations of 3D micro/nano-structures fabricated by LDW via TPP and specific structure characteristics such as composition\, morphology\, and surface chemistry. This approach allowed us to obtain better control over attachment\, growth\, and\, in some cases\, differentiation of various cell types\, e.g. osteoblasts\, fibroblasts\, and glial cells. We further improved the effectiveness of the laser-printed structures by volumetric integration of electrically and magnetically responsive biomaterials into the “backbone” of the structures. The electrically or magnetically “active” 3D micro/nano-structures allowed us to accelerate certain processes involved in tissue regeneration by externally applied electric or magnetic stimuli. \nWe expect this approach to emerge in advanced biomedical applications such as tissue engineering\, wound dressings\, and advanced drug delivery systems\, with the final goal of refining patient-oriented treatments. \n\n\n \n \n \n \n \n \n \n \n \n \n \n \n \n Watch the Talk URL:https://lasers4.eu/event/laserlab-europe-talk-boosting-multiphoton-3d-printing-for-biomedical-engineering-small-features-high-impact-2-april-2025/ CATEGORIES:Webinars ATTACH;FMTTYPE=image/png:https://lasers4.eu/wp-content/uploads/Thumbnail_paun.png END:VEVENT BEGIN:VEVENT DTSTART;TZID=Europe/Berlin:20250326T170000 DTEND;TZID=Europe/Berlin:20250326T180000 DTSTAMP:20260430T160759 CREATED:20250313T042553Z LAST-MODIFIED:20250710T105035Z UID:4433-1743008400-1743012000@lasers4.eu SUMMARY:Lasers4EU Webinar: Technology transfer and patenting: from fundamental research to a business model.

This organization is essential for regulating cellular functions\, as it enhances efficiency by minimizing the loss of intermediate products. While the compartmentalization of eukaryotic cells is well understood\, much less is known about the prokaryotic one. For a long time\, prokaryotic cells\, such as bacteria\, were believed to lack subcellular organization\, with biochemical reactions occurring in a disordered manner. However\, recent studies on metabolic pathways suggest a certain degree of subcellular organization within bacteria too that would facilitate enzyme proximity to enhance reactions kinetics. Although molecular biology provides different techniques\, such as two-hybrid systems\, to analyse molecular interactions\, imaging approaches are necessary to provide nanoscale spatial information about those interactions. \nIn our work we demonstrate how by combining Photo-Activated Localization Microscopy (PALM) with Expansion Microscopy (ExM) it is possible to perform three-dimensional simultaneous single-molecule co-localization and measure intermolecular distances with nanometres precision. The Ex-PALM approach is applied to study the spatial distribution of two enzymes\, HisF and HisH\, of the histidine metabolic pathway in Escherichia Coli bacteria whose interaction has already been demonstrated by previous studies. Using a plasmid-based transformation\, each protein was tagged with a photoactivable fluorescent protein (HisF-PAGFP\, HisH-PAmCherry) to enable single-molecule localization with nanometres accuracy. A negative control sample with two non-interacting enzymes\, HisH and aaC\, was also prepared to confirm our hypothesis that only interacting proteins co-localize. \nTo validate our theory\, we first improved three-dimensional multicolour PALM imaging by reducing crosstalk and chromatic aberrations. This step was essential\, as these aberrations are comparable in scale to the intermolecular distances of interest\, and failing to correct them would compromise single-molecule localization accuracy\, making it impossible to analyse densely packed subcellular structures\, such as those found in bacteria. Next\, we optimized the ExM protocol to achieve a 4.5-fold isotropic expansion of bacteria\, enabling the study of bacterial subcellular organization. To prove the reliability of our analysis method\, we applied it on both simulated and real data and found consistent results. \n \n Watch the LLE Talk URL:https://lasers4.eu/event/lle-talk-revealing-bacterial-subcellular-structure-with-three-dimensional-multicolour-super-resolution-microscopy/ CATEGORIES:Webinars ATTACH;FMTTYPE=image/png:https://lasers4.eu/wp-content/uploads/Thumbnail_caldini.png END:VEVENT BEGIN:VEVENT DTSTART;TZID=Europe/Berlin:20250305T100000 DTEND;TZID=Europe/Berlin:20250305T120000 DTSTAMP:20260430T160759 CREATED:20250407T105455Z LAST-MODIFIED:20250407T110331Z UID:4583-1741168800-1741176000@lasers4.eu SUMMARY:Lasers4EU Activity Board meeting\, 5 March 2025 DESCRIPTION:The Activity Board of the Lasers4EU project will meet on 5 March 2025\, 10:00-12:00 CET. \nThe link to connect will be shared by the Laserlab-Europe office. \n  \nThis is a project internal event.

Loukakos (IESL-FORTH)\nDate: Wednesday\, 29 January 2025\, 16:00 CET\nVenue: Online\n \nIn this talk I will present our recent work on the application of laser-surface processing in the fabrication of nanostructured metallic electrodes. These electrodes have been found to exhibit enhanced electrochemical properties and they have been used in water-splitting electrochemical cells where we have found that they produce almost 5 times as much Hydrogen when compared with flat metallic electrodes. The enhanced Hydrogen evolution reactivity and electrochemical properties are attributed to the concomitant enlargement of the electrode’s electrocatalytic area due to the nanostructured surface. The details of the experiments as well as the impact of applications of lasers in the energy and environmental sectors will be discussed.\n \n Watch the Talk\n \n \n \n \n \n This Laserlab-Europe Talk is coorganised by Lasers4EU and 360Carla.

Ohland (GSI Helmholtz Center for Heavy Ion Research)Date: Wednesday\, 18 December 2024\, 16:00 CET \nThe Apollon Real-Time Adaptive Optics (ARTAO) system addresses air turbulence-induced Strehl ratio fluctuations in Apollon\, the 10 PW Ti:Sapphire laser system in France. With a 50 m multi-pass amplifier and a 140 mm beam diameter\, turbulence previously caused significant beam quality instability. To resolve this\, the open-source AO platform CACAO\, originally developed for the Subaru Observatory\, was adapted for real-time beam stabilization using a continuous pilot beam. This marks a pioneering application of astronomical AO technology in ultra-high-intensity lasers. \nSupported by the EC funded THRILL project under its wavefront stabilization task\, ARTAO demonstrates a stability sufficient to achieve an on-shot Strehl ratio above 0.96 by evaluating 2.6 thousand wavefronts per second and controlling a deformable mirror at 1.3 kHz. \nThis technology has great potential for future applications: in Inertial Confinement Fusion (ICF) powerplants\, real-time AO will be indispensable for operating hundreds of laser beamlines at 10 Hz\, delivering MJ-scale pulses with minimal aberrations. By integrating AO into Adaptive Laser Architecture (ALA)\, these systems can overcome thermal challenges and meet the demands of fusion energy production. \nThis presentation will detail ARTAO’s development\, initial results\, and its potential role in the future of high-energy laser systems. \n \n Watch the LLE Talk URL:https://lasers4.eu/event/laserlab-europe-talk-from-telescopes-to-fusion-powerplants-real-time-adaptive-optics-for-high-power-lasers/ CATEGORIES:Webinars ATTACH;FMTTYPE=image/png:https://lasers4.eu/wp-content/uploads/Thumbnail-Ohland.png END:VEVENT BEGIN:VEVENT DTSTART;TZID=Europe/Berlin:20241120T160000 DTEND;TZID=Europe/Berlin:20241120T170000 DTSTAMP:20260430T160759 CREATED:20241107T121429Z LAST-MODIFIED:20250710T105332Z UID:2977-1732118400-1732122000@lasers4.eu SUMMARY:Laserlab-Europe Talk: Compressive Raman imaging: a computational framework for high-speed chemical microscopy DESCRIPTION:Title: Compressive Raman imaging: a computational framework for high-speed chemical microscopySpeaker: Hilton B. de Aguiar (CNRS\, Laboratoire Kastler Brossel and Ecole Normale Superieure)Date: Wednesday\, 20 November 2024\, 4:00pm CET \nRaman imaging is recognized as a powerful label-free approach to provide contrasts based on chemical selectivity. Nevertheless\, Raman-based microspectroscopy still have drawbacks precluding high-speed chemical imaging. The main issue is the inherent high data throughput in microspectroscopy: fast spectral imaging is challenging for dynamic and large-scale imaging due to its data acquisition\, processing and representation change (from vibrational resonances amplitudes to chemicals concentration) procedures. \nThese challenges can be overcome by exploiting the concept of compressive Raman imaging: by leveraging the sparsity [1] and redundancy [2] in Raman data sets\, one can develop computational procedures to considerably simplify and speed up the spectral image acquisition. Exploiting such framework\, we have recently reached speeds compatible with video-rate imaging [3] by detecting just a handful of photons. \nIn this presentation\, I will introduce and discuss the different ways of performing compressive Raman\, in particular focusing on challenges for bio-imaging\, and also show more recent results applied to long-time imaging of electrochemical systems [4]. \nReferences[1] Sturm et al\, ACS Photon. 6\, 1409 (2019); Scotte et al.

Among the various enabling tools\, electronic laboratory notebooks (ELNs) – designed to replace commonly used paper notebooks – offer notable benefits to users\, from supporting collaboration amongst researchers\, simplifying secured copying of data or time stamping to directly incorporating of instrument parameters. However\, there are a multitude of ELN products on the market [Nature Protocols 17\, 179 (2022)] and identifying the most appropriate and user-friendly one may be complex and time-consuming. \nThis Laserlab-Europe online workshop will present user experience (pros and cons) on some of the most popular ELNs (e.g. eLabFTW or Labfolder) as well as national initiatives on related topics such as metadata. Discussions will allow exchanging on pros and cons of ELNs and on how to motivate ourselves to switch from paper to an ELN. \nAgenda >> \n\n Notice: JavaScript is required for this content.\n\n\n \n\n\n \n \n \n  \n  URL:https://lasers4.eu/event/workshop-on-electronic-laboratory-notebooks/ CATEGORIES:Project END:VEVENT BEGIN:VEVENT DTSTART;TZID=Europe/Berlin:20241021T070000 DTEND;TZID=Europe/Berlin:20241022T160000 DTSTAMP:20260430T160759 CREATED:20240807T083601Z LAST-MODIFIED:20241202T073528Z UID:1872-1729494000-1729612800@lasers4.eu SUMMARY:Lasers4EU Kick-off Meeting\, 21-22 October 2024\, Crete\, Greece DESCRIPTION:Preliminary agenda \n21 October 2024\n09:00-13:00 Laserlab-Europe V General Assembly\n13:00-14:00 Lunch\n14:00-17:30 Lasers4EU Kick-off Meeting Day 1\n17:30-19:00 Lab Tour at IESL-FORTH\n19:30- Working Dinner \n22 October 2024\n09:00-15:30 Lasers4EU Kick-off Meeting Day 2\n16:00/16:30 Sightseeing Tour \n\n Notice: JavaScript is required for this content.
