A consistent and conceptually simple derivation is given for the basic integral equation of the scattered field in the presence of a phase-conjugate mirror characterized by a constant amplitude-reflection coefficient. This integral equation is exact, except for the fact that the incident field is assumed to contain no evanescent components and the effects of the evanescent waves are neglected at the phase-conjugate mirror.
