摘要
当用微波场作用到V型三能级原子的两个激发态能级时,系统跃迁路径之间发生交叉耦合导致了量子相干效应.本文通过调节微波场的强度,实现了对原子吸收和色散性质的改变,并在共振频率处呈现零吸收高折射率现象.此外,微波场诱导的量子相干也可实现相对相位对探测光增益的控制.
When the two excited levels in a V-type three-level atom are coupled by a microwave field, the quantum coherence is created by the interference between the atomic coupling transition channels. The probe absorption and dispersion properties can be modulated by adjusting the strength of microwave field, and the phenomenon of the high refractive index without absorption appears at the resonance. Be- sides, the relative phase control of probe gain can be achieved due to the quantum coherence induced by the microwave field.
