| 摘 要： | 将光束动态分布的概率分析加入到传统稳定性设计过程之中,提出了一种基于动态分布的光束稳定性分析方法,并以大型激光驱动器中的空间滤波器为分析对象,讨论了在不改变光学参数的基础上,如何利用该方法对滤波器的结构特性进行优化。结果表明,该方法能够对元件间的相对参数值提出要求,有别于传统方法仅着眼于提升单个元件的稳定性的设计思路。与传统方法共同运用,同时对光束的动态范围和分布类型进行优化,能够进一步改善系统的稳定性,为装置运行提供稳定可靠的基础平台。

| Abstract: | The probability analysis of dynamic distribution of beam positioning in high power laser facility is added to traditional stability design,and a stability analysis method based on dynamic distribution is proposed.Taking spatial filter in large laser facility as object,we discuss how to optimize its structural parameters by this method,with its optical parameters being constant.This method is aiming to constraint the relative stability of components in spatial filter,and it is different from the traditional ... |
