Abstract

Yb-Raman fiber amplifier is an effective solution to achieving high-power narrow linewidth fiber laser operating at 1100-1200 nm region, in which the selection of the pump source at around 1064 nm has a significant effect on the output power and spectral properties. In this paper, we report an Yb-Raman fiber amplifier pumped by a random fiber laser. Hundred-watt level output power with 3 dB spectral linewidth of only 0.23 nm is obtained by optimizing the linewidth of the random fiber laser. The results could provide a practical reference for the systematic design of the narrow linewidth Yb-Raman fiber amplifier.
