Abstract
We report on a ruggedized compact modular package narrow linewidth fiber amplifiers with 1.5kW linear polarized output in an all-PM fiber configuration and 2 kW in non-PM fiber configuration for various scientific and advanced applications. The fiber amplifiers have 2m output cable with connector termination for 15GHz linewidth and 20GHz linewidth in PM and in non-PM fiber configuration respectively. The fiber amplifiers have 40% wall-plug efficiency and 15nm spectral bandwidth for 1064nm wavelength range. Measured M2 values of the output beam of the amplifiers are < 1.1.
