Observation of resonances at subharmonics of the Rabi frequency in the saturated absorption of a 100% amplitude-modulated laser beam

Technical Report ·
OSTI ID:6287473
A series of resonances has been observed in the absorption of a 100% amplitude-modulated laser beam by an optically pumped sodium atomic beam. Resonances were observed when the modulation frequency was equal to the first, second, and third subharmonic of the Rabi frequency. The experimental results are compared with theory, and the implications of these parametric resonances to laser instabilities are discussed.
