Abstract

Abstract

A master oscillator power amplifier (MOPA) structured narrow-linewidth Yb-doped fiber laser is set up in all-fiber format. In the system, a single frequency laser is broadened to be a 0.3 GHz-linewidth seed by using noise phase modulation technique. The power of the seed is then scaled from 10 mW up to 666 W through a four-stage power amplifier chain. Further power-scaling of this MOPA system can be expected since our experiment is only pump-power limited.
