Breather phase transitions for a three-component transient stimulated Raman scattering system in nonlinear optics

Abstract

A three-component transient stimulated Raman scattering system in nonlinear optics is investigated. By applying the Lax-Darboux scheme, analytical breather solutions are constructed. A detailed investigation was performed for the breathers of the off-diagonal density-matrix element, Stokes wave and pump wave. The system possesses both general and Kuznetsov-Ma breathers. Furthermore, an exact link is established between the phase states and spectrum parameter. Via adjusting the spectrum parameter, the breathers exhibit novel phase transitions. The amplitudes and densities of the wave envelopes also vary at the different phase states.
