论文摘要
在大多数被困在光学晶格中的原子的实验中，光晶格束的横向大小在数十微米的范围内，并且尚未仔细研究将许多原子加载到较小的光学晶格中。我们报告捕获1500 $^{171} $ yb原子，该原子在狭窄的腔模式生成的一维光学晶格中，距离距镜面0.14毫米。从镜像磁光陷阱中加载原子的最简单方法与空腔模式重叠，可以通过调整均匀的偏置磁场来调节加载位置。被困在光学晶格中的原子数量显示了两个不同晶格深度的局部最大值，在较深的晶格中具有全球最大值。这些结果开辟了一种基于与紧密聚焦的光场的强相互作用的量子机械操作的方法。
In most experiments with atoms trapped in optical lattices, the transverse size of the optical lattice beams is on the order of tens of micrometers, and loading many atoms into smaller optical lattices has not been carefully investigated. We report trapping 1500 $^{171}$Yb atoms in a one-dimensional optical lattice generated by a narrow cavity mode at a distance of 0.14 mm from a mirror surface. The simplest approach of loading atoms from a mirror magneto-optical trap overlapped with the cavity mode allows the adjustment of the loading position by tuning a uniform bias magnetic field. The number of atoms trapped in the optical lattice exhibits two local maxima for different lattice depths, with a global maximum in the deeper lattice. These results open a way to quantum mechanical manipulation of atoms based on strong interaction with a tightly focused light field.
