Modelling of multiple soliton operation of fiber lasers with anomalous frequency dispersion

Abstract

On basis of numerical simulation we study the peculiarities of the formation of ultrashort pulses, their interaction, the formation of stable multiple soliton structures in passive mode-locked fiber lasers with anomalous frequency dispersion. It is found the novel type of a dissipative soliton. The single soliton of this type has asymmetric spatial and spectral profiles and demonstrates bistability: two stable states with right and left spectral-spatial asymmetries for which the single soliton velocities are different.
