150 W highly-efficient Raman fiber laser

2

Yan Feng, Luke R. Taylor, Domenico Bonaccini Calia
We report a more than 150 W spectrally-clean continuous wave Raman fiber laser at 1120 nm with an optical efficiency of 85%. A ~30 m standard single mode silica fiber is used as Raman gain fiber to avoid second Stokes emission. A spectrally asymmetric resonator (in the sense of mirror reflection ... [Opt.
