Abstract
In order to study stimulated Brillouin scattering（SBS） in Yb3+-doped double clad single-frequency fiber amplifiers, numerical simulation was carried out based on the rate equations. The results show that fiber length, pump schemes, pump power, heat transfer coefficient make great impact on SBS effect. On the other hand the impact of the signal power is small. The results of simulation provide a theoretical guide to optimum design of high power single-frequency fiber amplifiers.
