Resumen
We report the results of a simulation of the laser-induced breakdown spectra of graphite in an atmosphere similar to that of Mars using a non-equilibrium 3T-Eurlian fluid model. In our approach the atomic energy level populations were calculated using a collisional-radiative (CR) NLTE-model taking into account the mixing between the plasma and the ambiant gas. The simulation was performed with the FLASH radiation-hydrodynamics code. We have investigate the effects of laser irradiance and ambient CO2 pressure on the plasma parameters namely the electron and ion temperatures and the electron and ion densities and the temporal variation of the fluid velocity with the laser irradiance at constant pressure which indicate the presence of a shock front associated with the plasma initiation, dynamics, and expansion into the ambient gas.
