Spectral structure of stimulated Brillouin scattering

The behavior of the phase of the light scattered in stimulated Brillouin scattering in CC14 has been studied experimentally. The fundamental shape of the scattering spectral line in the buildup regime has been determined. Instead of the theoretically predicted Gaussian emission spectrum, the results reveal a reproducible fine structure of the line in the form of an asymmetric triplet in the Stokes region under ordinary experimental conditions. © 1995 American Institute of Physics.
