Abstract
An apparatus and method of producing a phase conjugate replica of a light beam involves internal reflection of the beam within a body of mixing material which lacks inversion symmetry. The orientation of the body relative to the incoming beam is adjusted such that at least one auxiliary beam splits off from the incoming beam, is internally reflected at least twice by the surface of the material and returns to the incoming beam within the material for scattering as an oppositely directed phase conjugate replica thereof.
