摘　　要：设计并研制了全固态连续单频1.34μm Nd:YVO4环形激光器。利用880nm激光二极管双端端面偏振抽运Nd:YVO4晶体,通过腔镜镀膜抑制1.06μm激光振荡和环形激光谐振腔的设计优化使激光器稳定单向行波运转,实验获得了输出功率达9W的连续单频1.34μm激光输出,光-光转换效率达18%。激光器在4h内的功率稳定性优于±1%,在1min内的频率漂移为8.5MHz,输出激光的光束质量M2因子为1.03。An all-solid-state continuous-wave （CW） single-frequency 1. 34μm Nd： YVO4 laser is designed and fabricated. Based on a polarized and dual-end pumping scheme, a Nd： YVO4 crystal is directly pumped by an 880 nm laser diode, the 1.06 μm laser is suppressed by the coating of cavity mirrors, and a ring resonator is designed. The measured maximum output power of 9 W at 1.34μm is obtained with optical-optical conversion efficiency of 18%. The stability of the output power is better than ± 1% over a period of 4 h and the frequency shift is less than 8.5 MHz in 1 min. The output beam is almost diffraction limited with a measured beam quality of M2 = 1.03.
