摘要
从分析当前我军炮兵普遍装备的1.06μm激光测距机对人眼的损伤出发,重点探讨了开发1.5xμm炮兵安全型激光测距机的具体措施,主要有三种方法:一是直接输出1.5xμm波段的激光;二是在激光测距机上加装喇曼池,通过SRS将其频率从1.06μm移到1.54μm左右;三是利用1.06μmNd:YAG激光泵浦的光学参量振荡器(OPO),采用KTP晶体Π类非临界相位匹配的OPO,输出1.57μm的参量光。
This text analyses the damnification to people′s eyes the 1.06 μm laser rangefinder applied in artillery largely, and probes into how to empolder the safety 1.5x μm rangefinder applied in artillery.It mainly has the three meanses as followes. Firstly, it outputs the laser 1.5x μm wave band directly; Secondly, shifts it frequency from 1.06 μm into about 1.54 μm by the means of SRS. Thirdly, it outputs 1.57 μm parameter light, using 1.06 μm Nd:YAG laser′s OPO, and by matching KTP crystal types Π non-critical ...
