Abstract

The laser induced plasma plume expansion in vacuum is studied by a Monte Carlo simulation. The global shape of the plume created above a copper target is followed in time by using a 3D algorithm. An original method has allowed the simulation with no restrictions on laser spot width or ablated depth. Particles evaporation from the sample surface during the laser pulse is done by introducing in the model a radial distribution of laser energy and a high surface temperature induced by the vapor pressure. The effects of the later energy absorption by the evaporated particles appear to be dominating parameters on the expansion process. An approximation of these effects has been done by considering a fraction of energetic species, corresponding to the recombination of ionic species by kinetic energy transfer in the cloud. Results of this simulation are compared with experimental results obtained by time of flight measurements and fast photography of the luminous component of the plume.
