Abstract
We demonstrate the excitation and low-noise detection of coherent population trapping (CPT) resonances with two modulated optical fields with orthogonal circular polarizations. When a microwave phase delay of λ/4 is introduced in the optical path of one of the fields, the difference in the power transmitted through the cell in each polarization shows a narrow, dispersive resonance that can be used, for example, to stabilize the frequency of an external oscillator. The differential detection allows a high degree of suppression of laser-induced noise.Citation
