摘要

采用解析和数值方法研究了弱激波在固体目标中的产生和传播过程。考虑波长(λ)为1.06微米、脉冲强度I为1010 ~ 1012w /cm2的激光脉冲的冲击为波源。在0.5-1 mm厚的固体介质中，研究了产生的压力约为1-100kBar的波。将模拟结果与实验数据进行了比较，证明了对给定问题的水动力近似的正确性。

Laser-generated weak shock wave propagation dynamics in the solids

The processes of the weak shock wave generation and propagation in the solid targets are studied by analytical and numerical methods. The impact of the laser pulse with wavelength (lambda) equals 1.06 micrometers and the pulse intensity I equals 1010-1012W/cm2 was considered as a wave source. The resulting wave with pressure about 1-100kBar is studied in a solid medium 0.5-1 mm thick. The results of modeling compared with experimental data shows correctness of hydrodynamical approximations for a given problem.
