摘要
为了解决半导体激光器出射光束发散角大的问题,对高斯光束远场性能进行了分析,得出不能采用常规的倒置望远镜方法实现半导体激光器光束准直的结论.针对一种5mW半导体激光器,提出使用组合透镜的方法使其实现光束准直.运用光学设计的PW方法,使用ODP2光学设计软件,设计了两组三片式组合透镜构成的光束准直系统,经过象差检验,准直效果好.
In order to solve the problem of big divergence angle of laser diode beam,the characteristics of Gauss beam in far field is analyzed and it is concluded that the typical way of inversing telescope is out of the question.The idea to use lenses assembly is presented.To collimate the beam of 5 mW laser diode,an optic system including two groups and three pieces of lens is desinged by PW method and ODP_2 optic design software.The beam can be collimated satisfactory because the aberration is much little.
