几何光学近似下X光激光的三维传播与放大
-
摘要: 采用放大自发辐射(ASE)模型何光学近似,在考虑折射效应而不考虑饱和 ,用几效应和等离子体老化的情况下,编制了单靶三维光路计算程序,给出了出射X射线激光的强度角分布和空间分布。在线聚焦等离子体线宽方向尺寸有限和横向密度梯度为0的条件下,研究了X光激光传播放大特性,重新审视了计算横向发射角时所用的公式。Abstract: In this paper, a program on Xray laser’s threedimensional propagation and amplification for single target is presented. ASE model and geometrical optics approximation are adopted. Without considering saturation andplasma ageing and with refraction effects taken into account, angle distribut ion and spatial distribution of Xray laser intensity with important data for saturation research and esti?
