SUMMARY:Laserlab-Europe Talk: From Telescopes to Fusion Powerplants: Real-Time Adaptive Optics for High-Power Lasers
DESCRIPTION: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 \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

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.

SUMMARY:Workshop on electronic laboratory notebooks
DESCRIPTION: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.  \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
