高功率固体激光器对入射的泵浦光具有严格的均匀性和工作深度要求。本文通过将微透镜阵列与长焦深菲涅尔透镜结合，对半导体激光器阵列光束进行整形，获得在长工作深度范围内的均匀光斑。本文针对 dilas E15Y-808.3-1260C半导体激光器阵列设计了目标光斑大小为4 mm×4 mm的三维激光整形系统。仿真结果表明，该光束整形系统与传统的多通道光束积分整形系统相比，在光斑尺寸与均匀性保持不变的情况下，工作深度增加了2倍。

High power solid state laser has strict requirements in the incident pump light. This paper reshape the beam of semiconductor laser array to a long working depth high uniform spot by combining microlens array and long focal depth Fresnel lens. A simulation system is designed, the input is from dilas E15Y-808.3-1260C laser array, and the final spot is 4mm × 4mm. The result show that compared with conventional system, the working depth is 2 times extended and the uniformity in work depth maintains the same. The design is useful and effective, and provides a feasible way to high power semiconductor laser array pumping source.
