| Popis: | — A novel green laser source, based on a monolithic cavity microchip laser platform, has been developed. The laser is designed to be a part of a miniature and efficient RGB light source for microdisplay-based mobile projector devices. The use of highly efficient, periodically poled MgO-doped lithium niobate as the non-linear frequency doubler allows for a significant increase in the overall efficiency of the green microchip laser. Specifically, a 50–150-mW green output with a wall-plug efficiency exceeding 10% in the temperature range of greater than 40°C has been demonstrated. A compact package for this laser source with a volume less than 0.33 cm3 is discussed and results of performance tests are presented. |
