Vectorial stimulated Raman scattering resolution on the semi-line

Stimulated Raman scattering between a laser pump pulse and a Stokes pulse is considered in a two-level medium with vectorial optical fields. The model on the semi-line is proved to be solvable by inverse scattering transform scheme. Among solutions, soliton generation is discussed. Then, it is shown how rotation of the Stokes wave leads to a spike of pump radiation in the time domain. -- Highlights: ► Vectorial stimulated Raman scattering is shown to be solvable on the semi-line by the inverse scattering transform scheme. ► Solitons can be created by pairs like in the scalar stimulated Raman scattering. ► Raman spike and multi-spike can occur in the time domain when considering rotating Stokes polarization.
