HEISENBERG APPROACH TO PHOTON-EMISSION NEAR A PHASE CONJUGATOR

An expression for the emitted fluorescence radiation by an atom near a phase conjugator is derived from a plane-wave expansion of the electric-field operator and Heisenberg's equation of motion for the annihilation operator. The result is compared to a solution that was found previously, based on the classical Maxwell equations. It is shown that both theories yield the same expression for the field in the radiation zone, in the limit of a transparent medium. This confirms the correctness of either approach to the problem of optical phase conjugation of atomic radiation.
