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。
An important factor to take into account when designing a high power laser range shooting range terminal optics (FOA) is the destruction of optical components by ghost images. Due to the high output energy of SG-II-U, the shooting range is small and the distribution of ghost images is complicated, the design of terminal optical components is very difficult. The self-developed Ghost Control Design Software is used to design the arrangement of the optical components of the Shouguang II upgrade device’s shooting range terminal. The design factors to be considered when designing the ghost image control are given. The design of the two shooting range optical devices The advantages and disadvantages of the program, and finally combined with the characteristics of SG upgrade device Ⅱ, the optimal design of the final device upgrade SGS optical device terminal arrangement.
