We review methods of combining beams using the Brillouin interaction. We analyze a two cell geometry that provides
both high gain amplification (G~300) simultaneously with high efficiency power conversion (η=90%). We consider
some configurations that could demonstrate this performance but note that their complexity makes them relatively
unattractive at this point in time.
