| Popis: | In this work an improved mathematical model for a metal ablation by femtosecond laser pulses is proposed. This model is constructed relying on two-temperature hydrodynamic model for electrons and ions and wide-range equation of state for metals. Results of the simulation 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. |
