多程放大系统总体光路的稳定性研究
-
摘要: 根据打靶精度要求分解系统的稳定性指标，利用光线追迹并通过三维矩阵与代数运算相结合的方法，开发了分析多程放大系统总体光路稳定性的仿真软件。针对神光-Ⅲ原型装置的总体光路的数学模型，完成了各单个元件稳定性对打靶弹着点的影响的模拟计算。Abstract: To give out the stability requirements of every components in the multi-pass amplification system of a large laser facility, a ray- tracing software was developed by using the method of 3×3 matrix and algebra. Using the developed software and by establishing a mathematical model of the layout of TIL, which is a multi-pass high power laser facility, the task of analyzing the relations between the stability of any individual optical component and the position of the beam focus on the target has been fulfilled.
