The response of a two-level atom driven by a strong resonant amplitude-modulated field is calculated in the Bloch model. The population difference and dipole moment show a resonant behaviour when the Rabi frequency is a multiple of the modulation frequency. This phenomenon is related to the resonant AC Stark effect and is the optical counterpart of the coherence resonances known in radiofrequency... Plus

    Summary
    The response of a two-level atom driven by a strong resonant amplitude-modulated field is calculated in the Bloch model. The population difference and dipole moment show a resonant behaviour when the Rabi frequency is a multiple of the modulation frequency. This phenomenon is related to the resonant AC Stark effect and is the optical counterpart of the coherence resonances known in radiofrequency magnetic resonance.
