Calculations of Brillouin backscatter in laser-produced plasmas. Memorandum report

TL;DRAbstract

Brillouin backscatter is calculated in an inhomogeneous laser produced plasma. Equations for the spatial dependence of the incident reflected and sound wave are numerically integrated through the underdense plasma. Effects investigated are the stabilizing effects of ion heating or nonlinear sound wave dissipation, flow velocity magnitude and gradient, electron heating and broad band incident laser light. We find that the effect of velocity gradient and broad band light can be very important in reducing the backscatter.
