Abstract

Recently, the use of Yb-Raman fiber amplifier has led to a breakthrough in the power of narrow linewidth laser at 1120 nm. In this paper, the effects of seed filtering on the output laser characteristics in a narrow linewidth Yb-Raman fiber amplifier are studied. The experimental results indicate that the seed filtering can not only suppress the ASE noise in the output laser, but also have an influence on the evolution of the sideband noise of the signal spectra. This work can contribute to the understanding of narrow linewidth Yb-Raman fiber amplifiers and can provide a reference for the systematic design.
