相干制备原子系综中的延迟四波和六波混频

Delayed four- and six-wave mixing in a coherently prepared atomic ensemble

D. Felinto, D. Moretti, R. A. de Oliveira, J. W. R. Tabosa

摘要:

我们报告的同时观察,延迟布拉格衍射,四波和六波混频过程中的相干制备的冷铯原子组成的原子系综。对于每个衍射阶,我们观察到不同的时间脉冲形状和依赖性与激发场的强度,证明了在每个过程中所涉及的不同机制。各种观测结果可以用一个简化的分析理论来描述,该理论将原子系统看作是一个三能级原子的Λ组态系综。

英文摘要:

We report on the simultaneous observation, by delayed Bragg diffraction, of four- and six-wave mixing processes in a coherently prepared atomic ensemble consisting of cold cesium atoms. For each diffracted order, we observe different temporal pulse shapes and dependencies with the intensities of the exciting fields, evidencing the different mechanisms involved in each process. The various observations are well described by a simplified analytical theory, which considers the atomic system as an ensemble of three-level atoms in Λ configuration.
