Abstract
We present a joint theoretical and experimental characterization of the coherent population trapping (CPT) resonance excited on the D(1) line of (87)Rb atoms by bichromatic linearly polarized laser light. We observe high-contrast transmission resonances (up to approximate to 25%), which makes this excitation scheme promising forminiature all-optical atomic clock applications. We also demonstrate cancellation of the first-order light shift by proper choice of the frequencies and relative intensities of the two laser-field components. Our theoretical predictions are in good agreement with the experimental results.
