1W narrow linewidth semiconductor based laser module emitting near 1064 nm for the use in coherent optical communication in space

Abstract

We report on the realization of a semiconductor laser based master oscillator power amplifier (MOPA) system with high output power and narrow linewidth. The system features an output power of more than 1W in stable single mode operation. The FWHM linewidth is 100 kHz and the minimum intrinsic linewidth is as small as 3.6 kHz. The laser concept presented… (More)
