Abstract

Stimulated Rayleigh-wing scattering (SRWS) excited by a nano- or picosecond laser pulse has been observed in liquid CS₂ by several authors.^1–4 Their experimental results concerning the spectral study of SRWS, indicate that the spectral bandwidth of scattering light can be either as small as that of the laser¹ or as large as several hundred cm⁻¹.^3,4 In this work we report that a large-bandwidth SRWS spectrum can be obtained not only in a waveguide but also in a bulk medium with a short active length, and we interpret it in terms of the molecules statistical orientations and the collision-induced anisotropy.
