Paper Abstract

Recent developments in compact projectors sparked interest in light sources for these applications. While RGB lasers offer advantages, a viable green laser platform has been difficult to realize. In this work, we demonstrate a novel green laser source, based on a monolithic cavity microchip laser platform. The use of highly efficient, periodically poled MgOdoped Lithium Niobate (PPMgOLN) as the nonlinear frequency doubler allows obtaining a significant increase in the overall efficiency of the green microchip laser. Specifically, we demonstrate 50-150mW green output with wall-plug efficiency exceeding 10% in the temperature range over 40°C. We discuss a compact package for this laser source with volume less than 0.4cm3.
