Paper Abstract

The influence of the delivery fibers, drawn by pump combiner or added initiatively, on stimulated Brillouin scattering (SBS) is discussed, based on the rate-equations combining with SBS. The impacts of pump schemes are simulated and the results indicate that the amplifier performance is considerable undermine by the delivery fiber in co- and counter- pumped amplifiers. As a suitable pump scheme for high power all-fiber amplifiers, we focus on the situation in the co-pumped amplifiers, in which the lengths, Brillouin gain coefficient and core diameter of the delivery fiber make great impacts on the performance of amplifiers. The impacts of the temperature gradients along the fiber, which can broaden the SBS gain profile and thereby suppress SBS, on the amplifier performances are discussed. Suitable suppression scheme is proposed to overcome the influences of delivery fiber on the amplifier performance.
