Adrien Leblanc partner in an ERC Synergy grant – Laboratoire d'Optique Appliquée

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.

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 !

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 !

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!

Quantum Features of High-Order Harmonics – Laboratoire d'Optique Appliquée

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.

Their observation of a displaced squeezed state is now published in @physrevresearch.bsky.social.

Continuous relativistic high-harmonic generation from a kHz liquid-sheet plasma mirror We report on continuous high-harmonic generation (HHG) at 1 kHz repetition rate from a liquid-sheet plasma mirror driven by relativistic-intensity near-single-cycle light transients. Through precise c...

Our recent paper in @opticapubsgroup.bsky.social Optics Letters presents the first relativistic plasma-mirror high harmonic generation on a liquid-sheet target.

This is a real game changer for plasma mirrors !

We were happy to receive Prof. Donna Strickland's visit today and show her around a few of our labs.

Absolutely everything at LOA runs thanks to her (and our former colleague Gerard Mourou's) Nobel-prize-decorated Chirped-pulse-amplification!

Selected candidates will then be invited to present their work to a national jury.

The CNRS is prioritizing applicants with 1 to 5 years of post-doctoral experience.

Interested candidates are strongly encouraged to reach out to Jérôme Faure or Cédric Thaury (find their email on the LOA webpage).

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.
