| Abstract: | The effect of ion acoustic harmonic production on stimulated Brillouin scattering is studied by solving numerically the coupled wave equations. Time and space dependent model includes the detuning and linear damping of the ion harmonic cascade and the mismatch due to density gradient. Several new interesting aspects in the behaviour of stimulated Brillouin scattering are discovered. |
