Annotation: The phase-conjugate mirror with an external pump, which is based on the degenerate four-wave mixing in a nanosuspension caused by gradient light force action on nanoparticles, is considered. A possibility of implementation of multistable mirror states corresponding to different average intensity of the light field is shown. Calculations of the reflection coefficient of the light wave with conjugate wave front have been carried out for the case of four-wave mixing at wavelength of light 532 nm in an aqueous colloid of polystyrene particles.

Keywords: phase-conjugate mirror, reflection coefficient, multivalued function
