Abstract We report on progress in development of the low‐cost highly efficient miniature green laser source for consumer electronics applications such as handheld and pocket projectors. The source is based on the monolithic cavity microchip with highly efficient periodically poled MgO‐doped Lithium Niobate as the frequency doubler. This design allows high power output while maintaining small package size. We demonstrate up to 250mW average power output with >13% overall efficiency from the new package with total volume of 0.23cm3. We also demonstrate modulation speed of 2MHz, which, to our knowledge, is the highest, reported for the green microchip laser.
