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 here may find application in coherent optical communication, specifically in space, or within future precision spectroscopy and quantum optics experiments in harsh environments.
