Abstract

An inversionless gain of anti-Stokes radiation above the oscillation threshold in an optically dense far-from-degenerate double- Α 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 of less than one photon per molecule, is shown.
