We report a high-finesse bow-tie cavity designed for atomic physics experiments with Rydberg atom arrays. The cavity has a finesse of 51,000 and a waist of 7.1 μm at the cesium D2 line (852 nm). With these parameters, the cavity is expected to induce strong coupling between a single atom and a single photon, corresponding to a cooperativity per traveling mode of 35 at the cavity waist. To trap and image atoms, the cavity setup utilizes two in-vacuum aspheric lenses with a numerical aperture (NA) of 0.35 and is capable of housing NA = 0.5 microscope objectives. In addition, the large atom-mirror distance (≳1.5 cm) provides good optical access and minimizes stray electric fields at the position of the atoms. This cavity setup can operate in tandem with a Rydberg array platform, creating a fully connected system for quantum simulation and computation.
我们报告了一种为里德堡原子阵列的原子物理实验设计的高精细度蝴蝶结腔。该腔在铯D2线（852纳米）处的精细度为51000，束腰为7.1微米。基于这些参数，预计该腔能在单个原子和单个光子之间诱导强耦合，对应于腔腰处每个传播模式35的协同性。为了捕获和成像原子，该腔装置使用了两个数值孔径（NA）为0.35的真空非球面透镜，并且能够容纳NA = 0.5的显微镜物镜。此外，较大的原子 - 镜距离（≳1.5厘米）提供了良好的光学通道，并使原子位置处的杂散电场最小化。这种腔装置可以与里德堡阵列平台协同运行，创建一个用于量子模拟和计算的全连接系统。
