Abstract

We report a kilowatt-level Raman fiber laser with an integrated Ytterbium-Raman fiber amplifier architecture. A high power Ytterbium-doped fiber master oscillator power amplifier at 1080 nm is seeded with a 1120 nm fiber laser at the same time. A 1.3 kW all-fiber Raman amplifier at 1120 nm with an optical efficiency of 70 % is demonstrated, limited only by the available pump power.
