冲击压缩下钨靶对514.5nm激光的漫反射率

DIFFUSE REFLECTIVITY OF SHOCK COMPRESSED TUNGSTEN TARGET TO 514.5nm LASER

在二级轻气炮上完成了一系列铜飞片平面碰撞钨靶的实验，并测量了钨靶在８５～２５０ＧＰａ的冲击压缩下，对波长５１４．５ｎｍ入射激光的漫反射率。实验结果显示：冲击压缩使钨靶表面的漫反射能力降低，但不是单调下降的。

A series of experiments of flat impact between copper flyer and tungsten target has been done on a two stage light gas gun and the diffuse reflectivity of tungsten target to 514.5nm incident laser was measured under 85～250GPa shock pressure.The experimental results show that shock compression degrades the reflecting ability of target surface,but the reflectivity doesnt reduce monotonously while shock pressure rises.
