冷原子系综中光的储存轨道angular momentum的坍缩和回复

Collapses and revivals of stored orbital angular momentum of light in a cold atomic ensemble

D. Moretti, D. Felinto, J. W. R. Tabosa

摘要:

本文报道了铯原子冷系综中光的轨道角动量的存储。我们利用布拉格衍射来恢复入射光场施加到原子相干性中的存储光学信息。所存储的信息可以通过施加的磁场进行操纵,并且我们能够观察到由于存储的原子塞曼相干性的旋转超过15 $μs$的时间而导致的崩溃和复兴。

英文摘要:

We report on the storage of orbital angular momentum of light in a cold ensemble of cesium atoms. We employ Bragg diffraction to retrieve the stored optical information impressed into the atomic coherence by the incident light fields. The stored information can be manipulated by an applied magnetic field and we were able to observe collapses and revivals due to the rotation of the stored atomic Zeeman coherence for times longer than 15 $μs$.
