在回顾复眼透镜对单光束光源的均匀化机制基础上，分析了复眼透镜对激光二极管(LD)阵列光源的光束均匀化机制。即对子光束分割叠加破坏相似性，对所有分割叠加后的子光斑进行叠加获得均匀性。在此基础上，以抽运薄片或者板条激光器需要高功率密度的均匀抽运光为需求，设计了基于复眼透镜的LD阵列光束整形系统，并给出了其中复眼透镜和积分透镜这两个关键部件的结构形式和相关参数。最后根据所设计的复眼透镜LD光束整形系统搭建了相应的实验光路并测试了整形后光斑不均匀性，测试表明不均匀性为9.8%，验证了对复眼透镜LD阵列光束整形的分析。

Reviewing the mechanism of fly′s eye lens homogenizing single beam source, the mechanism of fly′s eye lens homogenizing laser diode array is studied. Each single beam is split and superposed to break down the comparability between them, then the shaped beams are superposed to gain a uniform beam. Then a fly′s eye lens based beam shaping system for laser diode array, aiming to improve pumping intensity, is designed. The parameters of fly′s eye lens and integrating lens are given out. An experiment of the designed beam shaping system is done and the non-uniformity of result beam is measured, which confirms the analysis of fly′s eye lens homogenizing laser diode array.
