This review paper of the field of phase conjugation by stimulated Brillouin scattering (SBS) describes the fundamental work which has been performed to characterize the process, assess its ability to correct aberrations in an optical system, and evaluate its use in high energy laser applications. Basic characterization of the SBS process and scaling of threshold, reflectivity and conjugation fidelity are discussed. Work performed in the transient and CW regimes is reviewed. Experimental and theoretical investigations of multiline and broadband phase conjugation are presented.
