Extraordinary Behavior of Atoms Near a Phase Conjugator
Abstract
An atom near a phase conjugator (PC) is theoretically seen to behave quite differently than an atom in empty space or an atom near an ordinary (linear) surface. With two laser beams which pump the nonlinear crystal (PC), it is found that an atom in its ground state can fluoresce if it is sufficiently close to a PC. The possible mechanism involves the atomic transition dipole polarizing the PC, which then spontaneously emits a photon focused on the atom. With stimulated absorption and subsequent spontaneous emission, the net effect is that the atom remains in its ground state. Keywords: Phase conjugator; Transition dipole; Ground state fluorescence.
