光在“3+1”能级原子包围圈中的传输

Propagation of Light in an Ensemble of "3+1"-Level Atoms

Yong Li, C. P. Sun

摘要:

研究了量子探测光在“3+1”能级原子系综中的传播,当原子与另外两个经典控制场耦合时,系统的量子探测光在其中的传播特性。首先,我们通过原子集体激发的动力学代数方法计算了三光子共振情况下探测光在这种原子介质中的色散特性,如极化率和群速度。然后计算了两个经典控制光场对原子跃迁失谐量相同和失谐量不同情况下探测光的色散。我们的结果表明,在这两种情况下,电磁感应透明的现象可以发生。特别是在第二种情况下,我们可以找到两个透明窗口的探测光。

英文摘要:

We study the propagation of a quantum probe light in an ensemble of "3+1"-level atoms when the atoms are coupled to two other classical control fields. First we calculate the dispersion properties, such as susceptibility and group velocity, of the probe light within such an atomic medium under the case of three-photon resonance via the dynamical algebra method of collective atomic excitations. Then we calculate the dispersion of the probe light not only under the case that two classical control fields have the same detunings to the relative atomic transitions but also under the case that they have the different detunings. Our results show in both cases the phenomenon of electromagnetically induced transparency can accur. Especially use the second case, we can find two transparency windows for the probe light.
