Good agreement between Stimulated Brillouin Scattering (SBS) measurements and the convective theory of SBS in randomly distributed speckles has been achieved thanks to recent progress in both the experimental and the theoretical parts. Modification of SBS in presence of a secondary interaction beam demonstrates the sensitivity of SBS to initial ion density fluctuations in the plasma.
