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.

Owing to these unique capabilities\, MPL has emerged as a powerful manufacturing technique across a wide range of disciplines. The ongoing growth of MPL is closely linked to advances in material design and post-processing strategies. \nIn particular\, the composition of MPL photoresists\, including the presence or absence of photoinitiators\, plays a critical role in defining fabrication thresholds\, resolution\, and the optical properties of the resulting structures. While photoinitiators can enhance polymerization efficiency\, they may also introduce fluorescence and coloration\, limiting their use in certain applications. In contrast\, photoinitiator-free and doped systems offer alternative pathways toward improved optical performance. The interaction of these materials with femtosecond laser irradiation across multiple wavelengths provides additional flexibility for controlling polymerization and tailoring spectral response. \nAdditionally\, post-processing approaches\, such as calcination and surface coatings\, further extend the capabilities of MPL by enabling the fabrication of fully inorganic and spectrally adaptable architectures. These strategies enhance the functionality and stability of the fabricated 3D structures without fundamentally altering the initial material platform. \nOverall\, these developments demonstrate the potential of material-driven approaches in MPL for applications in photonics and optoelectronics. \nRegistration here URL:https://lasers4.eu/event/laserlab-europe-talk-materials-and-post-processes-for-multi-photon-lithography/ CATEGORIES:Webinars END:VEVENT BEGIN:VEVENT DTSTART;TZID=Europe/Berlin:20260505T143000 DTEND;TZID=Europe/Berlin:20260505T163000 DTSTAMP:20260430T160754 CREATED:20260217T135257Z LAST-MODIFIED:20260217T135349Z UID:7081-1777991400-1777998600@lasers4.eu SUMMARY:Lasers4EU Access Board meeting\, 5 May 2026 DESCRIPTION:The Access Board of the Lasers4EU project will meet on 5 May 2026\, 14:30-16:30 CEST. \nThe link to connect will be shared by the Laserlab-Europe office. \n  \nThis is a project internal event.

This interest is driven by the ethical dilemma surrounding the culling of non-productive day-old male chicks in layer-hen production and by the need to improve hatchery efficiency. Optical techniques are widely investigated for these applications\, but are challenged by the complex optical properties and heterogeneous structure of avian eggs. Here\, we show that chicken eggs display unusual photon trapping behavior due to the eggshell behaving like an integrating sphere\, considerably extending photon time-of-flight. Time-domain diffuse optical spectroscopy (TD-DOS) on egg phantoms\, supported by Monte Carlo simulations and post-dispersive filtering experiments\, rule out fluorescence as the source for the long photon time-of-flight. These results point to diffuse reflections at the inner surface of the eggshell as the source of the long photon time-of-flight. Despite these boundary effects\, the retrieval of internal bulk optical properties remains feasible via inversion of the diffusion approximation after selection of appropriate boundary conditions\, as was demonstrated in incubated eggs. Finally\, phantom experiments illustrate how the integrating sphere affects the temporal response of time-resolved Raman and fluorescence measurements\, highlighting critical challenges in non-invasive optical characterization of avian embryos. \n \n \n \n \n \n \n \n \n \n \n \n \n \n Registration URL:https://lasers4.eu/event/lle-talk-elucidating-the-photon-migration-effects-in-incubated-chicken-eggs-using-time-domain-diffuse-optics-20-may-2026/ CATEGORIES:Webinars END:VEVENT BEGIN:VEVENT DTSTART;VALUE=DATE:20260526 DTEND;VALUE=DATE:20260530 DTSTAMP:20260430T160754 CREATED:20251105T111059Z LAST-MODIFIED:20260214T095011Z UID:6476-1779753600-1780099199@lasers4.eu SUMMARY:Laserlab-Europe and Lasers4EU Annual and Users Meeting 2026\, 26-29 May 2026 DESCRIPTION: URL:https://lasers4.eu/event/joint-lle-l4eu-am2026/ LOCATION:HiLASE\, Dolni Břežany\, Czech Republic CATEGORIES:Project END:VEVENT BEGIN:VEVENT DTSTART;VALUE=DATE:20260609 DTEND;VALUE=DATE:20260612 DTSTAMP:20260430T160754 CREATED:20260217T153253Z LAST-MODIFIED:20260217T180255Z UID:7087-1780963200-1781222399@lasers4.eu SUMMARY:Lasers4EU Training | Experimental methods and data analysis for femtosecond and attosecond spectroscopies: transient absorption spectroscopy\, time-resolved photoelectron/photoion spectroscopy\, 9-11 June 2026 DESCRIPTION: URL:https://lasers4.eu/event/lasers4eu-training-experimental-methods-and-data-analysis-for-femtosecond-and-attosecond-spectroscopies-transient-absorption-spectroscopy-time-resolved-photoelectron-photoion-spectroscopy-9-11-jun/ LOCATION:Max-Born-Institute\, Berlin\, Germany CATEGORIES:Project,Trainings ATTACH;FMTTYPE=image/png:https://lasers4.eu/wp-content/uploads/training-mb1i.png END:VEVENT BEGIN:VEVENT DTSTART;VALUE=DATE:20260713 DTEND;VALUE=DATE:20260718 DTSTAMP:20260430T160754 CREATED:20260217T180639Z LAST-MODIFIED:20260217T181313Z UID:7101-1783900800-1784332799@lasers4.eu SUMMARY:Lasers4EU Training | Hands-on Course on MINDLAB: Manipulating and Investigating Neural Dynamics for Learning and Ageing in the Brain\, 13-17 July 2026 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.
