摘　　要：采用单块半非平面Nd∶YAG单频环形激光器和环形外腔倍频技术 ,获得了单频功率 2 4 9.5mW的 5 32nm波长的绿光输出 ,倍频效率 4 3.2 % ,实现了倍频腔与激光器之间的跟踪锁定 ,倍频光功率稳定性优于 1% ,理论计算与实验结果一致。A monolithic ring laser and an external ring cavity for frequency doubling are used to generate 532 nm green radiation. With MgO:LiNbO3 as a laser frequency doubling crystal, 249.5 mW second harmonic generation from 577 mW IR input power was obtained. The efficiency is 43.2% and power stability is better than 1%. Theoretical calculation is in agreement with the experimental result.
