摘要
采用软边光阑和多级空间滤波器组合技术实现了光束的空间整形和等像面传输 ,利用Fresnel光束传输计算程序对 4× 2× 3阵列式放大器参数测量系统进行了优化设计 ,分析了空间滤波器中小孔尺寸对光束波面传输的影响 ,并对优化设计结果进行了分析和讨论 。
The soft aperture slots and multi spatial filters had been used to transmit the same phase of laser beams, the characters measurement system of 4×2×3 multi slab amplifier design has been optimized by a program of Fresnel, where the sizes of pinholes of spatial filters which influence laser propagation have been analized here, the design optimization result also discussed, and the methods and results obtained in this paper are applicable to the design of high power solid laser amplifier system.
