研究了V或Lambda位形中偶极相互作用三能级原子集合的稳态行为随两个强相干驱动场的相对位相的变化关系。对于较大的样品，位相是一个方便的参数，可以快速填充或完全消除系综的囚禁态。作为应用，我们介绍了适当制备的原子样品作为光开关器件，并展示了它在控制集体稳态共振荧光强度方面的优点。
The manipulation of the steady-state behavior of a collection of dipole-interacting three-level atoms in a V or Lambda configuration is investigated as a function of the relative phase of two strong coherent driving fields. For larger samples, the phase is shown to be a convenient parameter to rapidly populate or depopulate completely a trapping state of the ensemble. As applications, we present the appropriately prepared atomic sample as an optical switching device and show its virtues in controlling the collective steady-state resonance fluorescence intensity.
