研究了Ce Nd∶YAG双掺晶体热传导冷却重复频率激光器的光轴漂移特性 ,采用Cr4 + ∶YAG被动调Q及定向棱镜谐振腔 ,在 5Hz工作频率、抽运能量为 7 35J ,连续工作时间为 1min的条件下 ,在机载激光器上获得了光轴漂移量近乎为零、激光输出稳定的理想效果
The optical axis drift characteristics of Ce Nd:YAG double-doped crystal heat conduction cooling repetition frequency laser were studied. The Cr4 +: YAG passive Q-switched and directional prism resonator was used. At 5Hz operating frequency, the pumping energy was 735J. The continuous working time was 1min under the conditions of the airborne laser obtained on the optical axis drift is almost zero, the laser output is stable and the desired effect
