Théorique, numérique Description
The present PHD work aims at exploring theorically and numerically the generation of fast
particle beams in ultra relativistic (abobve 1021 W/cm2) laser-overdense solid interaction by
using properly-structured or shaped targets. Surface characteristics inducing local
electromagnetic modes more intense than the laser field and where nonlinear and relativistic
effects play a major role will be investigated. It may lead to groundbreaking ultra-short
synchronized light and electron sources with applications in probing ultrafast electronic
processes. In this context, this theoretical and numerical study will allow to suggest new
experimental schemes feasible on the Apollon facility and multi-PW lasers.
