Modeling of a stimulated Brillouin scattering experiment with statistical distribution of speckles

The results of experimental studies of stimulated Brillouin scattering (SBS) from a laser beam smoothed with a random phase plate (RPP) in a preformed expanding plasma are compared with the statistical theory of SBS from an inhomogeneous plasma. Many observed features can be explained assuming that SBS occurs in randomly distributed speckles. This hypothesis naturally combines observed pump depletion effects within a speckle, with relatively minor SBS reflectivity of the whole interaction beam. {copyright} {ital 1996 American Institute of Physics.}
