1.6 GeV electrons, cleverly laser-plasma accelerated at LOA with a "small" 50-TW laser! doi.org/10.1103/pc2y...

LOA and @institutcurie.bsky.social compared laser-accelerated very-high-energy (140 MeV) electrons with conventional radiotherapy beams; demonstrating the same effects on cells, tissues, and organisms. A step toward clinical use of laser-plasma accelerators! www.sciencedirect.com/science/arti...

Multiscale Radiobiological Assessment of Laser-Driven Very High Energy Electrons Versus Conventional Electrons

This study systematically investigates the radiobiological effects of very high energy electrons (VHEE) generated by a laser-plasma accelerator (LPA),…

New preprint! arxiv.org/abs/2602.10882 We measure anti-bunching and witness quantum non-Gaussian states from high-harmonic generation. High-harmonics are generated in a strong field process with unique properties, distinguishing it from the established quantum light sources.

🚀Plasma Science Summer School!🌊 Join us on Porquerolles Island, France (June 21-27) to study: 🔹 Laser-plasma accelerators 🔹 Photon sources 🔹 Inertial fusion 🔹 Lab-Astrophysics 🎓 For PhDs & Early Career Researchers. 💰 All local costs covered! ⏳ Apply by March 27: plasmascience.fr/plasmascienc...

Kudos to our our colleague Adrien Leblanc who is a partner in the recently awarded ERC Synergy grant NP-QED ! Together with scientists from @cea.fr ,DESY and @urochester.bsky.social, he will develop experiments that turn vacuum itself into a nonlinear medium. loa.ensta-paris.fr/2025/11/12/a...

Looking for an M2 internship? Most of our offers are on our website here: loa.ensta-paris.fr/join-us/ Lots of experiments on some of the planet's coolest lasers, and lots of numerical simulations!

La fête de la science commence à l'Ecole @polytechniqueparis.bsky.social et continue demain. Venez demain le 04/10 visiter au LOA un laboratoire où nous accelerons des électrons par laser à >99,99% de la vitesse de la lumière, et où nous développons des applications médicales. A demain ! #fds2025

Boosting the energy and beam quality of laser-wakefield accelerated electrons with a plasma waveguide, first demonstrated at LOA in 2022 (www.nature.com/articles/s41...) has also worked at the APOLLON laser. We generated quasi-monoenergetic beams beyond 2 GeV ! loa.ensta-paris.fr/2025/09/30/q...

Every couple of years we move the whole lab for a few days away from the daily grind in Palaiseau to some beautiful location. For the LOA Days 2025, we went to the magnificent island of Porquerolles! loa.ensta-paris.fr/2025/09/30/t...

High-order harmonics are non-classcial! This has recently been further substantiated by @kittenstate.bsky.social and his colleagues of the QUANTUM group at LOA. loa.ensta-paris.fr/2025/09/09/q... Their observation of a displaced squeezed state is now published in @physrevresearch.bsky.social.

Antoine Cavagna is defending his PhD thesis today at LOA!

IMPALA, the method retrieving multi-spectral wavefronts from measured speckle patterns, co-developed and first demonstrated at LOA, is highlighted in the December issue of @opnmagazine.bsky.social: www.optica-opn.org/home/article...

This wonderful Macaron has been home-baked and laser engraved with an LOA logo by one of our brilliant PhD candidates. This is the kind of rich skill set you develop during a thesis at LOA! It tastes really good, too.

Today at LOA, Yuliia Mankovska defends her PhD thesis "High-precision probing of Laser-Plasma and electron beam-plasma interactions".
