Abstract
The evolution of the stimulated Brillouin scattering (SBS) instability in time and two spatial dimensions is studied analytically. An exact solution of the linearized equations governing SBS in a finite homogen eous plasma shows that this two-dimensional instability usually satura tes because of the convection of the ion-acoustic wave, regardless of whether the associated one-dimensional interaction is convectively or absolutely unstable. The steady-state intensity profile of the Stokes light wave is often highly two dimensional.
