Équipe "Interaction laser-plasma"
Laser-plasma interaction physics is focusing on all processes that govern the propagation of laser beams into plasmas as well as their coupling. Its understanding is then essential for many fields of applications from inertial confinement laser fusion to particle acceleration or production of secondary sources. The team's objective is to study the mechanisms involved in these processes for a wide range of interaction conditions: laser pulse duration (ns/ps), laser intensity (1014-1019 W/cm2) and plasma parameters (as electron density and temperature).
