This paper presents the first results obtained with the LULI2000 facility on the stimulated Brillouin scattering (SBS) instability developing at 527 nm on solid targets. We describe the experimental configuration, the plasma parameters and give first results of the SBS as function of laser intensity in these plasmas. The Brillouin reflectivity measured at maximum energy is 8%. The measurements are compared with the Brillouin backscattering expected from linear theory in the exponential density profile.
