激光器单频激光非平面环形腔单块结构键合晶体 lasers single frequency laser non-planar ring resonator monolithic structure bonded crystal

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TmYAG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TmYAG激光器, 获得了878 mW的2 μm单频激光输出, 光-光转换效率为18.8%。为了减小2 μm激光器的热效应, 采用一种新型的YAG+TmYAG+YAG键合单块非平面晶体结构形式并取得了良好的效果。

Abstract

The experimental results of LD pumped monolithic non-planar ring resonator (NPRO) single frequency Nd:YAG laser and LD pumped monolithic bonded crystal NPRO TmYAG 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 TmYAG 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+TmYAG+YAG crystal was designed and good results were obtained.
