Abstract

We report a novel nonresonant magneto-optical effect in cold atoms and present the optimized parameters of the biased magnetic field, the incident probe light intensity, and the probe detuning to obtain the maximal signal of the magneto-optical rotation. This detection scheme may further improve the stability of the cold atom clock.

I_{F S} = \frac{1}{4} I_{0} {(e^{- α_{+} ω l / c} - e^{- α_{-} ω l / c})}^{2} + I_{0} e^{- (α_{+} + α_{-}) ω l / c} \sin^{2} [\frac{(n_{+} - n_{-}) ω l}{2 c}],
