It is important to keep away from the ghost reflection point for the arrangement design of final optics assembly (FOA) in the high power laser facility. The high power output of the “SG-Ⅱ” upgrading laser, limited target field space and complicated ghost reflection distribution lead to the difficult design of the FOA. By using the ghost image analysis software designed by ourselves, we analyzed the ghost reflection distribution of the FOA. Then, the arrangement of two types of designs for the FOA was optimized. According to the characteristics of “SG-Ⅱ” upgrading laser, we obtained the design for the FOA, which can satisfy the system requirement exactly.

设计高功率激光装置靶场终端光学组件(FOA)时考虑的重要因素是鬼像对光学元件的破坏。由于神光Ⅱ升级装置(SG-Ⅱ-U)的输出能量高、靶场空间小、鬼像分布情况复杂,导致了终端光学组件的设计难度很高。用自主研发的鬼像控制设计软件对神光Ⅱ升级装置靶场终端光学组件排布进行设计,给出了进行鬼像控制设计时需考虑的设计因素,并对比研究了两种靶场终端光学组件设计方案的优缺点,最后结合神光Ⅱ升级装置的特点,优化设计出神光Ⅱ升级装置靶场终端光学组件的最终排布方案。
