摘要
A model that is based on the propagation equation and coupled mode theory is introduced in order to describe stimulated Raman scattering（SRS） effects in long tapered fiber amplifiers.Based on the presented model,fiber amplifiers with uniform and long tapered fibers are theoretically and numerically simulated.It can be drawn from the results of our simulations that the long tapered fiber has the advantage in suppressing SRS when applied in fiber laser amplifiers.Our results can provide guidance in the designing of system configuration in long tapered-fiber-based fiber laser systems.
