摘　　要：介绍激光扩束原理,阐述望远镜系统扩展高斯光束的规律。通过分析不同激光扩束望远镜系统的特性,选用卡塞格林系统来实现强脉冲激光发射系统的设计要求,设计结果不仅满足准直性要求,并且在目标距离处的光斑大小具有一定的可调节性。The principle of laser beam expasion is presented and the expanding rule of a Guass beam through a telescope system is explained. After the characteristics of several different laser beam expanding telescope systems are analyzed, the Cassegrain system is selected to meet the design requirement of an intensive pulsed laser transmitter system. The design result has shown that this optical design can not only meet the requirement of collimation, but also has a tunability for the beam width at a certain distance.
