摘　　要：许多应用中都需要激光光束强度均匀分布,或者按照设计要求对激光光束的强度相位分布进行特定调制,因此,有必要对各种光束整形技术进行研究。目前,已发展了多种激光光束整形技术,其中光束积分法原理简单,适用性广,因此基于此方法的光束整形技术具有很大的工程价值。主要介绍了基于棱镜、反射镜及微透镜阵列等光学元件的光束积分系统的组成情况,列出了典型整形光路,以及近年来在光束整形方面的研究进展。同时,介绍了在整形过程中上述方法的各自特点。Laser beams with evenly distributed or specifically modulated intensity profiles are required in many practical applications,thereby necessitating theoretical and experimental studies in laser beam shaping techniques.A variety of laser beam shaping methods,wherein the beam integration plays an important role as a result of its simple principle and wide applicability,have been proposed thus far.Therefore,it has great value in engineering.This study introduces the usage of optical components,such as prisms,mirrors,and micro-lens arrays,in beam integration systems.In this paper,the typical optical paths and recent progress are presented along with a discussion of the characteristics of these shaping methods.
