The context of this work concerns mechanical damage of porous ceramics induced by laser irradiation. The latter excites electrons of the material (energy gain), which in turn modifies its optical properties and the laser propagation itself. The pores in the material bulk also modify laser propagation, giving rise to interference and enhancement in the electric field, which then accelerate the electron dynamics and the laser energy deposition. The latter induces temperature and pressure gradients that form the shock wave responsible for damaging the material. Describing this system therefore requires coupling hydrodynamics with electronic and laser dynamics. The objective of this postdoctoral research is to model and study this complex system. The first part of the work consists in coupling existing codes describing laser energy deposition and hydrodynamics. The obtained code will then be used to carry out physical studies and understand the interaction mechanisms. In particular, the influence of porosity characteristics on shock formation will be studied.
