Polarization selective motional holeburning for high efficiency, degenerate optical phase conjugation in rubidium Academic Article uri icon


  • We have observed high reflectivity (>40) optical phase conjugation for a low pump intensity (100 mW/mm2), using degenerate four-wave mixing in rubidium vapor. The polarization of the beams were selected such that the diffracting grating was formed in the Zeeman sublevel coherence. We find that only a selected band of atoms moving at non-zero velocities contribute to this process, by forming, in the atom's frame, a non-degenerate double- system. This observation makes it possible to construct a simple, compact, and highly efficient phase conjugator using a semiconductor laser, without any modulators, for many applications, without any concern resulting from frequency mismatch between the probe and the conjugate. 2001 Elsevier Science B.V.
