3 W of 650 nm red emission by frequency doubling of wafer-fused semiconductor disk laser

3 W at genuine red wavelength of 650 nm has been achieved from a semiconductor disk laser by frequency doubling. An InP based active medium was fused with a GaAs/AlGaAs distributed Bragg reflector resulting in an integrated monolithic gain mirror. 6.6 W of output power at the fundamental wavelength of 1.3 mu m represents the best achievement reported to date for this type of lasers.
