| 摘 要： | 根据远距离激光跟踪瞄准系统对出射激光束的准直要求,设计了一个倍率18的激光扩束系统,系统地介绍了设计方法.按照高斯光束的透镜变换理论,计算了该扩束系统的正确离焦量,分析了系统的焦点偏移量对出射光束束腰位置和束腰半径的影响,指出扩束效率对焦点偏移量非常敏感,预测了精密调焦机构要注意的问题.

| Abstract: | In the laser's long-distance tracking and aiming system,collimated laser beam is demanded.To meet this requirement,a laser expander with the ratio of 18 was designed.In this paper,the design method of the laser expander is introduced systematically.Based on the theory of transformation of Gaussian beam through thin lens,the perfect distance of defocusing is calculated out,and the effect of defocusing on the location of exit beam waist and the radius of beam waist are analyzed.The analysis shows that the eff... |
