Large spectral bandwidth stimulated Rayleigh-wing scattering in CS2

Abstract
Large spectral bandwidth stimulated Rayleigh‐wing scattering (SRWS) induced by picosecond laser pulse has been investigated in bulk liquid CS2. The spectral broadening range of SRWS can reach up to 200 cm−1 on Stokes side. Many features of this scattering, such as the shift of the spectral maximum from excitation line and the temperature dependence, are presented. In order to explain the spectral broadening phenomenon, a possible mechanism based on collision‐induced light scattering is also discussed.
