Progress in high-power single frequency master oscillator poweramplifier

摘要

Master oscillator power amplifier (MOPA) is becoming the obvious choice in order to develop some high power single frequency laser sources. Its simplicity, reliability, robustness have already allowed the demonstration of some tremendous increase of the output power. In this paper we will report our latest results in the development of high power single frequency, single mode and single polarization MOPA systems. We were able to obtain an output power as higher as 500 W with still keeping the narrow linewidth proprieties of the source.
