Rabi Resonances Induced by an Off-Resonant, Stochastic Field
Abstract
When an atom interacts with a phase-fluctuating field of fairly arbitrary spectral character, the Fourier spectrum of atomic population variations manifests a "bright line" at the atomic system's Rabi frequency. This bright line is termed a Rabi resonance. Here, we generalize our previous studies of this phenomenon by considering the characteristics of the Rabi resonance when it is excited by an off-resonant stochastic field. We find both experimentally and theoretically that (i) the Rabi resonance occurs at the Rabi nutational frequency, omega = square root of (sq delta + sq w1) where delta is the detuning and w1 is the Rabi frequency, (ii) that the strength of the Rabi resonance is maximized when absolute value of delta equals w1, and (iii) that the strength of the Rabi resonance is an asymmetric function of detuning.
