Dissipative and non-dissipative solitons in the SRS- backscattering of laser radiation in underdense plasma

The process of stimulated Raman backscattering of laser pulse in underdense plasma is considered self-consistently in 1D model. Solutions to this problem in the form of backward-propagating bright solitons (the Stokes scattered pulse and the plasma density wave) coupled with the dark soliton in the pump laser pulse are found. These solitary solutions exist both in the non-dissipative (non-collisional plasma) case and in the dissipative (collisional plasma) case.
