Introduction

The Intense Lasers and Applications Center (CELIA) is a joint research unit (UMR5107) founded in 1999 by the University of Bordeaux and the CNRS, joined in 2003 by the CEA. CELIA was created following the decision to install the Mégajoule laser in Aquitaine. Its main missions are to develop researches in intense laser sources, their interactions in extreme regimes with matter, plasmas and their applications in connection with large scale laser infrastructures (LMJ / PETAL), societal objectives or with high potential for technological development. This fundamental, theoretical and experimental research is accompanied by a strong contribution to university education and doctoral training.

CELIA currently brings together 104 people, including 41 researchers and teacher-researchers and 17 permanent technicians and engineers. It hosts and trains around 40 doctoral students and 10 post-docs of many nationalities.

CELIA brings together skills in fields that lie at the frontiers of fundamental physics and high-tech applications.

The topics developed in the laboratory are:

  • The physics and technology of intense high average power femtosecond lasers.
  • The laser / matter interaction in extreme regimes which is declined through:
    • Attoscience, including the realization of XUV attosecond harmonic sources, their metrology and their applications.
    • The study of ultra-fast dynamics in atoms, molecules, nanoparticles and condensed matter.
    • Plasma physics (High Energy Density and Ultra High Intensity) encompassing X plasma sources, hot and dense plasmas, inertial confinement fusion, laboratory astrophysics, relativistic particle acceleration.
  • Laser processes for precision machining and nanostructuring of materials by laser in pico and femtosecond regime or correlative plasma spectroscopy.

CELIA offers a platform of laser sources, XUV-X beamlines with state of the art dedicated instrumentation. This platform is open to external, national access, in a joint call to Lidyl and LOA laboratories, and European, via the LaserLab-Europe infrastructure network. CELIA is developing its high average power laser capabilities to unprecedented levels within the framework of CPER LEAP. The PLEXUSS project aims to extend its reception capacities via a new platform of ultra-high repetition rate laser sources.

CELIA is involved in many transversal and structuring projects (GPR Light, Fédération Chi-NOA), European projects (ERC EXciters, ERC-POC FASTEE) or programs (Eurofusion,) or international programs (LIA LUMAQ).

CELIA plays a special role supporting the Laser LMJ / PETAL installation in facilitating its openness to the academic community. It trains many doctoral students in physics that can be carried out on large laser infrastructures. He contributes to it through theoretical aspects, development of dedicated diagnostics, and active participation and force of proposal for the academic experiences program. He also plays a key role in the Laser-Plasma Association (ALP).

CELIA maintains strong and fruitful relationships with industry through collaborative projects and transfer or development actions. CELIA is a leading academic member in the ecosystem supported by the “route des lasers et des hyperfréquences” competitiveness cluster. In particular, CELIA contributes to projects with a strong societal impact and affecting the fields of health (XPULSE, POPRA, etc.). He is one of the privileged partners of the ALPHANOV Technology Transfer Center. The technologies and studies carried out at CELIA are at the origin of the creation of 5 start-ups and companies corresponding to more than 250 induced jobs.

CELIA is a particularly active initiator of excellent university training which stands out particularly for its involvement in EUR Light S&T, the PYLA continuing education platform and its international ERASMUS + ETI-ELLI or POWERLAPS offers. It trains many highly sought-after doctoral students in high-tech industry or joining research organizations.
