Laserlab-Europe Talk: Electromagnetic pulse generation by sub-nanosecond kilojoule laser pulses, 8 Oct 2025
2025-10-08 08:00 - 17:00 (Europe/Berlin)
Speaker: Jakub Cikhardt (Czech Technical University)
The interaction of a focused high-power laser with matter results in the generation of an electromagnetic pulse (EMP). 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.
In recent years we have achieved some interesting results, such as

the observation of unprecedentedly broad EMP bandwidths;
the dependence of the EMP spectrum shape and upper cut-off frequency on the laser beam energy/power, target material and target ground impedance;
the relation between EMP emission and the escaped electron energy spectrum;
the influence of the wave plate on the emission of charged particles and EMP; and
the characterization of the EMP caused by laser interaction with various gas targets.

As 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.

Laserlab-Europe Talk: Laser ablation propulsion: high power pulsed laser irradiation and advanced experimental investigation
2025-09-17 16:00 - 17:00
Speaker: Séverine Boyer (MINES-Paris/PSL)
Orbital debris removal in low Earth orbit (LEO) opens the way to a new paradigm in space propulsion. 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.

Laser Spectroscopy and Photonic Technologies for Circular Economy: Advancing Sustainable Innovations in Material Research and Diagnostics, 19-20 June 2025
2025-06-19 - 2025-06-21 | Heraklion, Heraklion, Crete, Greece
The workshop “Laser Spectroscopy and Photonic Technologies for Circular Economy: Advancing Sustainable Innovations in Material Research and Diagnostics”, is a dynamic event dedicated to exploring the transformative role of photonic technologies in fostering sustainability and innovation.
This workshop will primarily focus on laser spectroscopy, imaging, and sensing technologies, exploring their critical role in material research, diagnostics, and sustainable innovation. 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.
The program will also feature a poster session, providing a platform for researchers and students to present their work, exchange ideas, and foster new collaborations.
Two hands-on sessions will offer participants practical experience in:

Hyperspectral Imaging – exploring its powerful capabilities in material analysis and diagnostics.
Laser Spectroscopy – delving into its versatile applications in environmental monitoring, quality control, and material characterization.

Apply until 31 May 2025

Who should attend

This 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:

Researchers and Academics working in material science, photonics, environmental science, chemistry, and related fields who want to explore advanced diagnostic tools and sustainable applications.
Industry Professionals from sectors such as recycling, manufacturing, environmental monitoring, and quality control seeking innovative solutions for material analysis and circular economy practices.
Graduate and PhD Students aiming to expand their knowledge and hands-on experience in hyperspectral imaging and laser spectroscopy.

Whether 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.

Hands-on sessions

Hyperspectral Imaging
Unlike 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.
Laser Spectroscopy
This 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:

LIBS: 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.
Raman: 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.

Following 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.

The 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).
The event is endorsed by Laserlab-Europe through EU’s Horizon Europe co-funded project Lasers4EU (GA No 101131771).

Laserlab-Europe Talk: Glass drilling with femtosecond laser in GHz-burst mode, 18 June 2025
2025-06-18 16:00 - 17:00
Watch the Talk

Speaker: Inka Manek-Hönninger (University of Bordeaux, CNRS-CELIA)
Femtosecond laser materials processing in the GHz-burst mode has attracted much attention in the last few years [1,2], especially for top-down percussion drilling in dielectrics thanks to the outstanding machining quality of the holes [3]. 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.

Laserlab-Europe Talk: Optical modification of graphene for applications, 23 April 2025
2025-04-23 16:00 - 17:00
Speaker: Mika Pettersson (Laserlab-NSC)
Graphene and other 2D materials have many excellent properties but seldom they can be used as such in advanced applications. 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.
In 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.

Laserlab-Europe Talk: Boosting multiphoton 3D printing for biomedical engineering: small features, high impact, 2 April 2025
2025-04-02 16:00 - 17:00
Speaker: Irina Alexandra Paun (INFLPR)

The biomedical engineering sector is one of the most rapidly growing industrial areas, bringing together engineering, medicine and biology, to develop novel technologies for medical treatment. 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.
In 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.
We 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.

Laserlab-Europe Talk: Revealing bacterial subcellular structure with three-dimensional multicolour super-resolution microscopy, 5 March 2025
2025-03-05 16:00 - 17:00
Speaker: Chiara Caldini (LENS)
Cellular compartmentalization is the separation of the cellular interior into distinct compartments, each with specific conditions and materials, that enable the simultaneous execution of different metabolic processes. 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.
In 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.
To 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.

Title: Laser-surface processing for green Hydrogen and energy storage applications
Speaker: Panagiotis A. Loukakos (IESL-FORTH)

Venue: Online

In 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.

Laserlab-Europe Talk: From Telescopes to Fusion Powerplants: Real-Time Adaptive Optics for High-Power Lasers
2024-12-18 16:00 - 17:00
Title: From Telescopes to Fusion Powerplants: Real-Time Adaptive Optics for High-Power LasersSpeaker: Jonas B. Ohland (GSI Helmholtz Center for Heavy Ion Research)Date: Wednesday, 18 December 2024, 16:00 CET
The 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.
Supported 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.
This 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.
This presentation will detail ARTAO’s development, initial results, and its potential role in the future of high-energy laser systems.

Laserlab-Europe Talk: Compressive Raman imaging: a computational framework for high-speed chemical microscopy
2024-11-20 16:00 - 17:00
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
Raman 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.
These 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.
In 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].

Workshop on electronic laboratory notebooks
2024-11-13 09:30 - 13:00
Early and open sharing of research data is one of the key Open Science practices that still needs to be improved in our labs. 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.
This 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.
