Coherence-controlled transparency and far-from-degenerate parametric gain in a strongly-absorbing Doppler-broadened medium | | Thomas F. George

7 Aug 2000 | | Subject: | Quantum Physics; Optics; Atomic Physics | quant-ph physics.atom-ph physics.optics | | Affiliation: | Office of the Chancellor / Departments of Chemistry and Physics & Astronomy, University of Wisconsin-Stevens Point, Stevens Point, U.S.A) and A. K. Popov (Institute for Physics, Russian Academy of Sciences, Krasnoyarsk, Russia | | Abstract: | An inversionless gain of anti-Stokes radiation above the oscillation threshold in an optically-dense far-from-degenerate double-Lambda Doppler-broadened medium accompanied by Stokes gain is predicted. The outcomes are illustrated with numerical simulations applied to sodium dimer vapor. Optical switching from absorption to gain via transparency controlled by a small variation of the medium and of the driving radiation parameters which are at a level less than one photon per molecule is shown.
