Abstract We use the relative phase difference of two bichromatic fields of equal frequency differences for the coherent control of spontaneous emission of a three-level atom in the Λ configuration. Effects such as selective and total cancellation of fluorescence decay are obtained simply by varying the phase difference. The phase dependence of fluorescence spectra is attributed to the fact that the four different field components induce the transitions in a closed loop configuration.
