摘　　要：报道了激光二极管(LD)抽运单块非平面环形腔(NPRO)Nd:YAG激光器和LD抽运单块键合晶体非平面环形腔Tm:YAG激光器实现单频运转的实验结果。采用LD抽运的单块非平面环形腔Nd:YAG激光器,分别获得了1.876 W和616 mW的1064 nm和1319 nm的单频激光输出,对应的光-光转换效率分别为53.4%和19.2%。采用LD抽运单块键合晶体非平面环形腔Tm:YAG激光器,获得了878 mW的2μm单频激光输出,光-光转换效率为18.8%。为了减小2μm激光器的热效应,采用一种新型的YAG+Tm:YAG+YAG键合单块非平面晶体结构形式并取得了良好的效果。The experimental results of LD pumped monolithic non-planar ring resonator （NPRO） single frequency Nd：YAG laser and LD pumped monolithic bonded crystal NPRO Tm： YAG laser are proposed. 1064 nm and 1319 nm single frequency lasers with the power up to 1. 876 W and 616 mW were obtained from the LD pumped NPRO Nd： YAG lasers, and the optical-optical efficiencies were 53.4 % and 19.2 %, respectively. The 878 mW single frequency 2 μm laser was generated in the LD pumped monolithic NPRO Tm： YAG laser, with the optical-optical efficiency of 18.8 %. For reducing the influence of heat effect in 2 μm laser, a novel double-bonded YAG＋ Tm2 YAG＋YAG crystal was designed and good results were obtained.
