Abstract
The technique of near forward laser scattering is used for the first time i n an ignition-relevant laser plasma to obtain a background and laser driven fluctuation spectrum. The fluctuations cause beam spray which can affect t he symmetry in an inertial confinement fusion experiment. These results pro vide a benchmark for developing numerical models of beam spray.
