摘要:

实验证明,利用四波混频(FWM)效应,85 Rb原子中的轨道角动量(OAM)印记的红外线通过阶梯型组态线性转换为可见光.同时,我们对这种线性转换过程进行了理论模拟,理论分析与实验结果吻合较好。采用大的单光子失谐过程来减少原子对上转换光的吸收,避免四波混频过程中的斑图形成。多模图像线性变换过程在图像通信、天体物理和量子信息等应用中具有重要意义。

英文摘要:

We experimentally demonstrated that infrared light imprinted with orbital angular momentum (OAM) was linearly converted into visible light using four-wave mixing (FWM) via a ladder-type configuration in 85Rb atoms. Simultaneously, we theoretically simulated this linear conversion process, and the theoretical analysis was in reasonable agreement with the experimental results. A large single-photon detuning process was used to reduce the absorption of the atoms to the up-converted light and to avoid pattern formation in the FWM process. The multi-mode image linear conversion process is important for applications including image communications, astrophysics and quantum information.
