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。 By adding the probability analysis of beam dynamic distribution to the traditional stability design process, a beam stability analysis method based on dynamic distribution is proposed. Taking the spatial filter in large laser driver as the analysis object, Based on the optical parameters, how to use this method to optimize the structural characteristics of the filter. The results show that the proposed method can make the relative parameter values ​​between components different from the traditional design method, which only focuses on improving the stability of a single component. In combination with the traditional method, optimizing the dynamic range and distribution type of the light beam can further improve the stability of the system and provide a stable and reliable basic platform for the operation of the device.
