为探索研究飞秒激光在材料中驱动冲击波的相关特性，采用激光脉冲频域干涉测试技术对脉冲宽度35 fs、脉冲能量0.7 mJ、功率密度1014 W/cm2量级的飞秒激光脉冲在200 nm厚铝膜中驱动冲击波的过程进行了实验测量。通过测量冲击波在铝膜中的渡越时间，获得激光脉冲在铝材料中驱动的冲击波平均速度约为6 km/s；通过对不同时刻铝膜自由面频域干涉场测量结果的分析，获得铝材料自由表面速度达1 km/s，根据平面冲击波的关系，推算其冲击压强达到9 GPa。

The frequency-domain interferometry has been used to study the properties of shock waves driven by the femtosecond laser. The observation results of shock waves driven by a 0.7 mJ, 35 fs pulse laser with the intensity of 1014W/cm2 level in a 200 nm-thick aluminum film were presented. From the transit time varying with the thickness of aluminium film, the shock velocity was measured to be about 6 km/s. The measured frequency-domain interferograms showed that the rear surface velocity was 1 km/s, and according to the relation of planar shock waves, the shock pressure was calculated to be 9 GPa．
