Patent abstract
A semiconductor laser diode that internally converts one or more short wavelength “pump” beams to an output beam at a longer wavelength using nonlinear optical frequency conversion in the semiconductor. Modal phase matching of the pump and output beams in a semiconductor waveguide allows the conversion process to proceed with high efficiency.
