摘　　要：用国产半导体激光二极管泵浦Nd∶YVO4晶体,通过优化膜系,调节1064nm谱线的线性损耗以达到与弱谱线1342nm增益匹配,在室温下实现1064nm和1342nm双波长连续运转,并通过Ⅰ类临界相位匹配LBO晶体腔内和频在国内首次实现593.5nm黄色激光连续输出,当泵浦注入功率为1.8W时和频黄激光最大输出达85mW,光光转换效率为4.7%,功率稳定性24h内优于±2.8%.A design of LD-pumped Nd:YVO4 laser that generates simultaneous laser action at the wavelengths 1064 nm and 1342 nm by optimizing film design is presented. An optimized CW 593.5 nm yellow laser at room temperature is obtained for the first time. Using type-I critical phase-matching LBO crystal, 593.5 nm yellow laser is obtained by 1064 nm and 1342 nm intracavity sum-frequency mixing. The maximum laser output power of 85 mW is obtained when a incident pump laser of 1.8 W is used. The optical-to-optical conversion up to 4.7%, the power instability in 24 h better than ±2.8%.
