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 (MOT) 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.

将171Yb原子俘获成一维细腰的一维光学晶格

在大多数将原子捕获在光学晶格中的实验中，光学晶格束的横向尺寸约为数十微米，并且尚未仔细研究将许多原子装载到较小的光学晶格中的情况。我们报告陷阱1500${}^{171}$一维光学晶格中的Yb原子，通过窄腔模在距镜面0.14 mm的距离处生成。从与腔模重叠的镜像磁光阱（MOT）加载原子的最简单方法是通过调整均匀的偏置磁场来调整加载位置。对于不同的晶格深度，捕获在光学晶格中的原子数量表现出两个局部最大值，在更深的晶格中具有全局最大值。这些结果为基于与紧密聚焦的光场的强相互作用进行原子的量子机械操纵开辟了道路。
