发射冷原子的单脉冲磁聚焦实验

Experimental single-impulse magnetic focusing of launched cold atoms

David A. Smith, Aidan S. Arnold, Matthew J. Pritchard, Ifan G. Hughes

摘要:

本文报道了垂直发射冷原子的单脉冲三维磁聚焦。四个不同的配置的透镜被用来改变相对的径向和轴向聚焦特性。在所有四种构型中都能看到85 Rb的致密聚焦云。结果表明,原子-光线矩阵描述透镜作用的方法是不够的。使用透镜的磁场的完全近似的数值模拟显示出非常好的协议与透镜的径向聚焦特性。然而,轴向(垂直方向)的聚焦性能是不太好的描述,并讨论了其原因。

英文摘要:

Single-impulse three-dimensional magnetic focusing of vertically launched cold atoms has been observed. Four different configurations of the lens were used to vary the relative radial and axial focusing properties. Compact focused clouds of 85Rb were seen for all four configurations. It is shown that an atom-optical ray matrix approach for describing the lensing action is insufficient. Numerical simulation using a full approximation to the lens's magnetic field shows very good agreement with the radial focusing properties of the lens. However, the axial (vertical direction) focusing properties are less well described and the reasons for this are discussed.
