摘要

本文提出了一种改进的飞秒激光脉冲烧蚀金属的数学模型。该模型是根据电子和离子的双温流体力学模型和金属的宽范围状态方程建立的。对几种金属在不同激光辐照度和脉冲持续时间下的烧蚀深度进行了数值模拟，并与实验数据进行了比较。结果与实验结果吻合较好。

Computer Simulation of Metal Ablation by Single and Multiple Ultrashort Laser Pulses

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.
