Diode-pumped Nd:YVO4 CW 593.5 nm Yellow Laser with LBO Intracavity Sum-frequency Mixing
LD泵浦Nd:YVO4/LBO腔内和频连续黄光激光器

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%.
