本文提出了利用两束共传播拉盖尔-高斯光束干涉图样形成的环形阱操纵原子干涉仪的新结构。原子系综的相干分裂和合并是原子干涉仪必不可少的,它是通过两束LG光束的干涉图样来实现的。沿着光束传播方向,单阱阱演变成双阱阱,然后重新组合成单阱阱,可用于形成原子干涉仪。
In this paper, we proposed new constructions of atom interferometers manipulated through the toroidal trap formed by the interference patterns of two co-propagation Laguerre-Gaussian (LG) beams. The coherent splitting and merging of the atomic ensemble, which is essential for the atom interferometer, is realized by the interference pattern of two LG beams. Along the beam propagation direction, a single-well trap is evolved into a double-well trap and then recombined back into a single-well trap, which can be used to form an atom interferometer.
