论文摘要
在特定的采符状态下制备原子合机是许多用于实现量子传感器和量子记忆的协议的关键步骤。这些设备也可以从光纤集成中受益。在这项工作中，我们描述了实验结果，该实验结果由$^{87} $ rb原子在空心核心光子晶体纤维内的$^{87} $ rb原子的理论模型支持。观察到的泵送F = 2的人口增加了50％，M $ _f $ = 2 Zeeman替代了剩余的Zeeman替代的人口，使我们能够在F = 2中替代M $ _F $ = 2的相对人群的3倍，而M $ _f $ = 2在F = 2中替换了M $ $ $ $ $ _f $ _f $ _F = 2 f = 2 f = 2的f = 2。基于我们的理论模型，我们还提出了进一步提高碱填充的空心芯纤维的抽水效率的方法。
Preparation of an atomic ensemble in a particular Zeeman state is a critical step of many protocols for implementing quantum sensors and quantum memories. These devices can also benefit from optical fibre integration. In this work we describe experimental results supported by a theoretical model of single-beam optical pumping of $^{87}$Rb atoms within a hollow-core photonic crystal fibre. The observed 50% population increase in the pumped F=2, m$_F$=2 Zeeman substate along with the depopulation of remaining Zeeman substates enabled us to achieve a 3 times improvement in the relative population of the m$_F$=2 substate within the F=2 manifold, with 60% of the F=2 population residing in the m$_F$=2 dark sublevel. Based on our theoretical model, we also propose methods to further improve the pumping efficiency in alkali-filled hollow-core fibres.
