摘要
研究了电光调Ｑ及Ｃｒ４＋：ＹＡＧ被动Ｑ开关的二极管泵浦Ｎｄ：ＹＡＧ激光器，获得了１１ｍＪ的电光调Ｑ及被动Ｑ开关激光脉冲，Ｑ开关效率分别为７５％和３２％。以Ｃｒ４＋：ＹＡＧ被动Ｑ开关的激光器为基础，研制了二极管泵浦的Ｎｄ：ＹＡＧ激光测距机样机。以＜３ｍＪ的激光脉冲，无发射天线压缩发射，采用等效口径为Φ２６ｍｍ的接收天线。在～３Ｋｍ的能见度下，实现了３３９Ｋｍ的测距。最大测程为４７Ｋｍ（５Ｋｍ能见度），整机工作频率为１６ｐｐｓ，自然传导冷却。
Qswitched,diode pumped Nd:YAG lasers have been achieved through E-O Q-switch and passive Qswitch with Cr4+:YAG as saturable absorber.The giant pulse outputs were 11mJ,respectively with the Qswitching efficiencies of 75% and 32.3%.Based on the passive QSwitched laser head,a laser rangefinder prototype has been developed with effective receiver aperture of 26mm and without transmitter optics.
