We demonstrate very high-contrast coherent population trapping[1] (CPT) resonances by using four-wave mixing in Rb 87 atoms. In the experiment, we take advantage of the spectral overlap between F = 2 F and F = 3 F optical resonances on the D 1 line of Rb 87 and Rb 85 atoms, respectively, to eliminate the DC-light background from the CPT resonance signal. We observe a CPT resonance with a contrast in the range of 90%, compared with a few percent achieved by alternative methods.
