A compact and high power green-light source has been developed in diode-pumped solid-state laser based on periodically poled Mg:LiNbO 3 (PPMgLN). Optimization of the PPMgLN length in Nd:YVO 4 intracvity can achieve wide operation temperature range over 30 °C with maintaining high conversion efficiency. Based on this result, we demonstrated 3 cm 3 laser module which generated continuous-wave 0.7-W green light with wall-plug efficiency as high as 11.8%.
