LD纵向泵浦腔内倍频激光器腔参数的选择
Optimization of Cavity Parameters of LD End-pumped Intracavity Frequency Doubled Lasers
摘要
从理论上研究了在一定长KTP情况下LD纵向泵浦Nd:YVO4/KTP腔内倍频激光器的绿光输出与腔长、输出镜曲率半径及泵浦光斑半径等参数的关系。根据分析选择了一组实验参数,在入射泵浦功率为668.7 mW时获得了153.9 mW的绿光输出,光一光转换效率为23%。将实验结果与理论计算值进行了比较,两者符合较好。
Abstract
A theoretical ahalysis of laser diode end-pumped intracavity frequency-doubled lasers is presented. It is shown that the output SHG power depends mainly on the pumping beam waist,cavity parameters and the round trip loss of the cavity. An experimental result of a LD pumped Nd: YVO4 laser is reported. The second-harmonic output power at 532 nm is 153.9 mW at an incident pump power of 668.7 mW, corresponding to an optical efficiency of 23%.
