Abstract

We experimentally investigate optical storage with electromagnetically induced transparency in a dense cold (85)Rb atomic ensemble. By varying the optical depth (OD) from 0 to 140, we observe that the optimal storage efficiency has a saturation value of 50% as OD>50. Our result is consistent with that obtained from hot vapor cell experiments.

摘要

我们在密集冷 (85)Rb 原子系综中实验研究了电磁感应透明中的光存储。通过改变光学深度（OD）从 0 到 140，我们观察到当 OD>50 时，最佳存储效率具有 50%的饱和值。我们的结果与热蒸汽室实验得到的结果一致。
