摘要
The resonance fluorescence from a three-level Lambda atom is studied, in which each optical transition is driven by a coherent field and the metastable states are coupled to each other via a microwave field. It is shown that the fluorescence depends not only on the relative intensities of the coupling fields but also on the relative phase delay between the envelopes of the amplitudes of the three fields. For the case of equal intensity of the two coherent fields, the fluorescence is completely inhibited once the phase delay is set to be 0 or pi, while the fluorescence emerges once the phase delay is changed to pi/2; moreover, the fluorescence spectrum ultimately reverts to an ultranarrow triplet by decreasing the relative intensity of the coherent field to the microwave field.
