Semiclassical theory and numerical modeling for stimulated rotational Raman scattering in homonuclear diatomic molecules

The semiclassical theory of nonresonant stimulated rotational Raman scattering (SRRS) in homonuclear diatomic molecules has been developed. Multiple rotational lines, the full degeneracy of the molecule, Stark shift, and four-wave mixing effects are considered. An arbitrary number of optical fields is allowed. The polarization state of the fields is dynamically computed during the propagation. A numerical code has been written in a user-friendly format based on the theoretical model with diffractive effects included. Numerical results which display the code capabilities are presented and comparisons to available experimental data are shown
