| 摘 要： | 采用波长为0.35 μm的高功率激光脉冲聚焦辐照楔形铝靶，用光学条纹相机观测靶背面冲击波加热发光的特性。并对冲击波压力的定标关系和楔形样品冲击波速度的计算方法进行了介绍，对实验结果进行了简要的分析。结果表明：实验测量的冲击压力与定标公式的结果较为接近。

| Abstract: | Experimental records of the light emitting from heating luminescence at the rear surface of wedge-shaped aluminum target were obtained by an optical streak camera. The target was irradiated by a focused high power laser beam with 0.35 μm wavelength. The scaling relation between shock wave pressure and velocity was determined using wedge-shaped samples. The experimental results showed that shock wave pressure was close to the pressure estimated from the scaling relation. |
