LD-pumped Nd: YVO4 Crystal LBO Frequency-doubling 457nm Blue Laser
摘要
用国产半导体激光二极管泵浦Nd: YVO4晶体,在室温下获得914 nm激光连续输出,用Ⅰ类临界位相匹配LBO腔内倍频获得457 nm蓝色激光输出.当泵浦注入功率为1.7 W时倍频蓝激光最大输出达20 mW,光光转换效率为1.2%,功率稳定性24 h内优于±3%.
Abstract
A design of LD-pumped Nd∶YVO_4/LBO blue laser at 457 nm is presented in the paper.An optimized-designedCW914nmlaseratroomtemperatureisobtained.Usingtype-Icriticialphase-matchingLBOcrystal,457nm blue laser is obtained by 914 nm intracavity frequency doubling. The maximum laser output power of 20 mW is obtained when a incident pump laser of 1.7 W is used. The optical-to-optical conversion is up to 1.2%, the power instability in 24 h is better than ±3%.
