    "abstract": "We obtain, for the first time, an analytic theory of the forward stimulated\nBrillouin scattering instability of a spatially and temporally incoherent laser\nbeam, that controls the transition between statistical equilibrium and\nnon-equilibrium (unstable) self-focusing regimes of beam propagation. The\nstability boundary may be used as a comprehensive guide for inertial\nconfinement fusion designs. Well into the stable regime, an analytic expression\nfor the angular diffusion coefficient is obtained, which provides an essential\ncorrection to a geometric optic approximation for beam propagation.",
