Computer modelling of pulsed laser femtosecond ablation for metals

In this article a mathematical model for a femtosecond pulsed laser ablation for metals is proposed. This model is based on two-temperature model for electrons and ions with addition of hydrodynamic part and wide-range semi-empirical equation of state for metals. The results of the modelling for several metals are compared with experimental data at different laser fluence and duration of pulses for ablation depth. A good agreement with them and the experiment is received. (paper)
