Abstract

A theoretical and numerical analysis of one-dimensional (1 + 1) vector spatial solitons in a laser with saturable absorption is conducted. The active medium is modeled by a four-level spin-flip scheme, while the absorbing medium is described by a two-level scheme, with the response of both media assumed to be fast. Stable stationary, mono- and bichromatic solitons, as well as breathers, are obtained. Transitions between different types of localized structures under variations of the scheme parameters are presented.
