Abstract
An all-fiber laser system is presented with a simple MOPA configuration composed of a seed laser followed by a one-stage high-power amplifier. The seed delivers 10 W of output power at 2036 nm. The high-power amplifier operates with a high slope efficiency of 59%. An output power of 937 W is demonstrated with a close to diffraction limited beam quality. No nonlinear effects were observed.
