论文摘要
我们提出了基于毫米球镜头的磁光陷阱（MOT）设计，其中包含在0.75 $^{\ prime \ prime} $侧长的金属立方体内。我们提供的证据表明，$ 4.2 \ times 10^5 $的$^{85} $ rb原子的数字密度为$ 3.2 \ times 10^9 $ atoms/cm $ $^{3} $，加载时间为1.3 s。测量和动力学激光冷却模型用于表征原子陷阱设计。该设计比其他类型的MOT提供了多种优势：激光功率需求较低，小镜头和立方体尺寸允许将MOT应用微型化，并且缺乏大直径光束途径可防止外部黑体辐射进入陷阱区域。
We present a magneto-optical trap (MOT) design based on millimeter ball lenses, contained within a metal cube of 0.75$^{\prime \prime}$ side length. We present evidence of trapping approximately $4.2\times 10^5$ of $^{85}$Rb atoms with a number density of $3.2\times 10^9$ atoms/cm$^{3}$ and a loading time of 1.3 s. Measurement and a kinetic laser-cooling model are used to characterize the atom trap design. The design provides several advantages over other types of MOTs: the laser power requirement is low, the small lens and cube sizes allow for miniaturization of MOT applications, and the lack of large-diameter optical beam pathways prevents external blackbody radiation from entering the trapping region.
