| 摘 要： | 为使发射光束以会聚形式传播,进行了室外450 m和300 m激光聚焦实验.将扩束准直后的光束通过伽利略望远系统,采用精密位移台调整负透镜与正透镜间距,实现不同距离的光斑聚焦.然后用功率计测量450 m焦点处的功率均值为47.67 mW,标准偏差0.67 mW.并利用光束质量分析仪测量聚焦光斑的能量分布.进而采用Matl...

| Abstract: | In order to lead the laser beam transmit in the atmosphere convergently,an experiment of laser focus at a distance of 450 m and 300 m has been operated in outdoor place.The actual manipulations are as follows: Firstly,the laser is collimated by a beam expander,then the near-parallel laser beam transmits through a Galileo telescope system,and the distance between the concave lens and the convex lens can be tuned through a precise displacement platform,so the focus of the system can change due to the tiny dis... |
