Abstract

Phase conjugation of two beams by stimulated Brillouin scattering (SBS) was studied with a computer model and investigated experimentally. The relative phase of the return beams was found to vary randomly if the pump beams were well separated in the SBS cell but remained fixed and equal to the inverse of the pump relative phase if the beams overlapped. Backward Stokes injection was used to lower the threshold and increase the reflectivity of SBS.
