利用两个等频差双色场的相对相位差，对Λ位形中三能级原子的自发辐射进行相干控制。通过简单地改变相位差，就可以获得选择性和完全消除荧光衰减的效果。荧光光谱的相位依赖性归因于四个不同的场分量在闭合环构型中诱导跃迁的事实。
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.
