Modeling of pulsed-fiber sources

We review what we have learned in the last few years from modeling nanosecond fiber amplifiers. We have developed a number of models that treat bent fiber mode profiles and bend loss, plus gain models and models of nonlinear processes such as self phase modulation, self focusing, SRS, SBS, and four wave mixing. The models have been validated by detailed comparisons with laboratory measurements.
