Abstract : This report describes a one-year program to investigate phase-preservation and cleanup in a double-pass Raman amplifier (RA) by a stimulated Brillouin scattering (SBS) conjugator. The goal of this program was to determine the physical processes that limit the compensation of RA phase aberration by SBS conjugators. Departures from this ideal performance are caused by nonreciprocal aberrations and/or imperfect performance of the SBS conjugator. The purpose of this work was to quantify the distortions caused by nonreciprocal aberrations in the RA process for uniform as well as distorted pump and seed waves. Keywords: Raman amplifiers; Stimulated brillouin scattering; Phase conjugation; Nonreciprocal aberrations; High energy lasers.
