Abstract

The influence of laser beam smoothing on stimulated Brillouin backscattering (SBBS) reflectivity was studied analytically. It was shown that the temporal beam smoothing can reduce the SBBS reflectivity significantly even though the laser bandwidth is smaller than the growth rate for the average intensity. The dependence of this reduction effect on the acoustic damping for a given laser bandwidth is discussed.
