Laboratoire pour l’Utilisation des Lasers Intenses, Palaiseau, France
Research centre dedicated to high-energy laser-matter interaction in the nanosecond, picosecond and femtosecond regimes, LULI operates two multi-beam laser facilities: APOLLON, a Ti:Sapphire shot-per-minute facility offering an exceptional multi-PW peak power, and LULI2000, a highly energetic Nd-glass laser.
Access to the APOLLON laser facility allows studying laser-matter interaction in the yet unexplored ultra-relativistic regime and developing applications, especially those of the energetic and ultra-short secondary sources produced at intensities up to 2 1022 W/cm2. Topics currently under investigation are electron acceleration (using single- & multi-stage schemes), ion acceleration (exploring advanced schemes to break the 100 MeV limit or to produce neutron and positron sources, tackling warm dense matter physics and laboratory relativistic astrophysics), x-ray production (harmonics from solid targets, FEL-type or betatron sources) and high-field physics (to study QED effects in laser-plasma interaction). Experimental research is supported by numerical simulations using the SMILEI open-source PIC code.
LULI2000 couples high-energy and high-power laser pulses onto a target together with external high-amplitude pulsed magnetic fields. The experiments re based on laser irradiation of solid or gaseous targets to produce high-energy density matter at extreme temperature and pressure conditions, often in out-of-equilibrium regimes. The versatility of the facility and the scientific expertise of the LULI host researchers allows covering many fields of research, from fundamental - magnetized or not - plasma physics to shock-loaded material investigation, inertial fusion sciences, laboratory astrophysics and planetology. Laser-based secondary sources of high-energy particles and radiation are commonly used for innovative diagnostic techniques or for warm dense matter production.
The facilities offer access to gas & solid target characterization laboratories, target alignment benches and a large palette of state-of-the-art instrumentation. Laser diagnostics are implemented on the whole set of laser beams.
