    "abstract": "An inversionless gain of anti-Stokes radiation above the oscillation\nthreshold in an optically-dense far-from-degenerate double-Lambda\nDoppler-broadened medium accompanied by Stokes gain is predicted. The outcomes\nare illustrated with numerical simulations applied to sodium dimer vapor.\nOptical switching from absorption to gain via transparency controlled by a\nsmall variation of the medium and of the driving radiation parameters which are\nat a level less than one photon per molecule is shown.
