Paper Abstract

The instability of hot spots leading to angular spreading and frequency broadening of a spatially randomized laser beam has a much lower threshold for collisional plasmas compared to the collisionless regime. The plasma-induced spatial and temporal incoherence in forward-propagating light is consistent with the forward stimulated Brillouin scattering (SBS). It also serves to reduce the reflectivity of backward SBS. The interaction of randomized beams with collisional plasmas produces the angular and frequency spectra of transmitted light that are much broader and smoother than in the collisionless regime.
