| 摘 要： | 利用光学高速阴影照相,研究了激光在透明介质中的传播。有如下结果:(1)比较了两种不同激光波长上(λ1=1.3μm及λ2=0.44μm),在具有相同吸收激光强度下,所产生的不同冲击波压力。(2)分析了冲击波压力对靶面吸收激光功率的依赖关系。

| Abstract: | We have carried cut experiments on laser-driven shock wave propagation in a transparent target using high-speed shadowgraphy. The results of the following studies are obtained: 1) A comparision of shock wave pressures at the two wavelengths (λ =1.3μm and λ = 0.44 μm). 2) Scaling of shock wave pressures in dependence on the absorbed laser intensities of the targets. |
