Spontaneous emission of fluorescence radiation by an atom near the surface of a four-wave mixing phase conjugator is considered. It is shown that the spectral photon distribution consists of two Lorentzians, which have their peaks symmetrically located at the two sides of the pump frequency omega bar of the nonlinear crystal. With omega sub 0, the atomic resonance, the line at 2 omegabar-omega sub 0 is more than twice as strong as the line at omega sub 0. When the phase-conjugate reflectivity exceeds unity, the temporal photon distribution exhibits nonclassical behavior. Then, antibunching of photons prevails, and the photon statistics is sub-poissonian.
