47.4: 1 Watt Compact Green Laser for Projection Display

Abstract In this paper, we demonstrate a compact efficient diode pumped solid state green laser based on a periodically poled MgO:LiNbO 3 crystal, which is suitable for low‐cost mass production. A linearly polarized 532 nm laser light greater than 1.02 Watt CW power was obtained, which corresponds to an optical‐to‐optical conversion efficiency of 37.2%.
