Abstract
The gain/feedback approach to lasing and optical instabilities has been applied to sodium vapor driven by a near-resonant intense field. The observed lasing frequencies agree with the two-beam-coupling gain curve calculated for a Doppler-broadened two-level medium. Rayleigh-gain lasing is seen with no external cavity using counterpropagating beams, and Raman gain lasing is seen in a ring cavity.
