Initial development of supercontinuum in fibers with anomalous dispersion pumped by nanosecond - long pulses

Abstract

We propose and compare with experimental data a two-stage model of supercontinuum formation in a fiber for nanosecond-long pulse with intensities in 10 W range. As a result of the first stage, the sea of solitons is formed. The second stage is spectrum modification because of Raman interaction.
