| 摘 要： | 基于对Nd:GdVO4晶体热焦距的测量及其1.06 μm激光基本性能,用三镜折叠腔研究了半导体激光器(LD)泵浦的Nd:GdVO4/KTP晶体的内腔倍频性质.当用从直径为200 μm的单光纤输出的低功率的半导体激光泵浦时,绿光的阈值是26 mW,光光转换效率为17.3%.当用从直径为1.55 mm的光纤束输出的高功率的半导体激光泵浦时,绿光的阈值是200 mW,光光转换效率为19.35%.

| Abstract: | Based on the measuring of thermal focal length and 1.06 μm fundamental property of Nd:GdVO4, the intracavity-frequency-doubling property of LD pumped Nd:GdVO4/KTP laser has been studied with a three-mirror folded cavity. When pumped by low power LD laser outputted from a single-fiber with the diameter of 200μm, the green laser has a threshold of 26 mW and an optical-to-optical efficiency of 17.3%. When pumped by high power LD laser outputted from a multi-fiber with the diameter of 1.55 mm, the green laser has a threshold of 200 mW and an optical-to-optical efficiency of 19.35%. |
