Extraordinary Behavior of Atoms Near a Phase Conjugator

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.
