Numerical stability computation of ultrashort pulse generation in erbium fiber laser passively mode locked through nonlinear polarization rotation

Abstract

Nowadays ultra-short pulse lasers are of the great interest in laser physics and material science. The popular scheme of ultra-short pulse fiber laser is based on nonlinear polarization rotation. However, the big drawback of this scheme is pulse generation dependence on resonator parameters. In our work, we have simulated process of pulse generation with different external parameters, such as dispersion, nonlinearity, birefringence, pump power and round-trip losses.
