摘要: 用几何光学计算了柱形腔壁上的激光光斑参数, 包括光斑的位置、形状、大小以及光斑内的光强分布, 同时还计算了在激光注入孔的光斑参数, 这对分析靶丸的初始辐射均匀性、确定腔壁上的辐照强度大小和判断能否将激光有效地注入腔内都是非常重要的。Abstract: The parameters of the laser on the wall of a cylindrical hohlraum and at the laser entrance holes have been calculated using geometry optics, including the position,shape and side of laser spots, as well as the intensity distribution inside the spots. The results are useful for analyzing the initial irradiation uniformity on the capsule and the irradiance on the wall of hohlraum and for effectively injecting laser into the hohlraum.
