78.4: Compact High Power Modulated Green Laser for Laser Display

Abstract In this paper we report a modulated laser‐diode pumped microchip green laser based on optical‐contact Nd:YVO 4 /periodically poled MgO:LiNbO 3 (Nd:YVO 4 /PPMgLN) crystal. A linearly polarized green light peak power as high as 541.5 mW was obtained for the first time, which corresponds to an electrical‐to‐optical efficiency of 13.9%. The maximum electrical‐to‐optical efficiency was 16.25%.
