Quenching and enhancement of an optical nonlinearity by a phase-conjugate mirror.
The nonlinear polarizabilities of a two-level atom and a nonlinear oscillator in front of a resonant phase-conjugate mirror are calculated as functions of the mirror reflectivity. The effect of the mirror is to quench the nonlinearity of the two-level system and most anharmonic oscillators. In the case of a weakly anharmonic oscillator the nonlinear polarizability can be extremely large.
