Abstract:
Compact and efficient green lasers are of high interest to consumer electronics applications such as handheld and pocket projectors. Since direct green laser sources are not available, a number of second-harmonic-based approaches have been proposed recently. However, challenges in low-efficiency and high-cost structure have not been successfully overcome yet. We demonstrate a novel green laser source based on the monolithic cavity microchip laser platform. The use of our highly efficient, periodically poled MgO-doped Lithium Niobate as the frequency doubler allows obtaining significant increase in the overall efficiency of the green microchip laser. Specifically, we demonstrate 200 mW green output with > 10% wall-plug efficiency in the 35°C temperature range.
