摘　　要：In this Letter, we report on the successful optical storage of orbital angular momentum（OAM） using Rydberg electromagnetically induced transparency（EIT） in cold rubidium atoms. With a storage time of 1.4 μs, the retrieved structure is highly similar, showing the ability of storing light＇s OAM at a principal quantum number of 20. The results at higher principal quantum numbers（n ？ 25; 30） are also measured. These results show the promise of image processing based on a Rydberg atomic system.In this Letter, we report on the successful optical storage of orbital angular momentum（OAM） using Rydberg electromagnetically induced transparency（EIT） in cold rubidium atoms.
