Paper Abstract

We present numerical simulations of transverse stimulated Brillouin scattering (SBS) in large aperture optical elements and investigate its suppression due to finite laser bandwidth. A specific model for the laser bandwidth, namely, a sinusoidal phase modulation of the electric field, is considered. Our calculations indicate that bandwidths larger than the SBS linewidth lead to significant reduction in the SBS gain. We also investigate the dependence of the SBS gain on the modulation frequency and find that for a fixed overall bandwidth, a modulation frequency of the order of the SBS linewidth leads to an optimal reduction of the SBS gain.
