高功率激光装置中的三倍频Nd∶YLF模拟激光系统

Third-harmonic Nd∶YLF Simulating Laser System in High Power Setup

基于高功率激光装置———“神光Ⅱ”中的三倍频模拟激光光源的需要 ,提出并研制了一套Nd∶YLF调 Q 三倍频激光作为模拟光源 ,采用氙灯抽运 ,Cr4+∶YAG被动调Q ,KTP晶体与BBO晶体的组合三倍频 ,得到了Nd∶YLF晶体的 1 0 5 3μm波段的三倍频 0 35 10 μm波长激光 ,满足了系统的需求。

To meet the requirement of the high power setup SGⅡ,a set of Q switched and tripling Nd∶YLF laser system for simulating light source is developed, the flash pumped Nd∶YLF laser used Cr 4+ ∶YAG crystal as the Q switch, KTP and BBO crystal as the third harmonic generator. Here a laser output of 0 3510 μm wavelength is got, and can satisfy the need of the SGⅡ system.
