论文摘要
我们开发了一种用于冷原子的超紧凑高分辨率成像系统。它唯一的空中元件是一种多模光纤，直径为$ 230 \，μ$ m，同时收集光并将其引导从真空室中引导。外部自适应光学元件使我们能够以$ \ sim 1 \，μ$ m分辨率在$ 100 \ times 100 \，μ$ m $ m $^2 $视野视野上对冷RB原子进行成像。这些光学元件可以很容易地重新排列，以在快速吸收成像和高敏荧光成像之间切换。该系统特别适合混合量子工程平台，在该平台中，冷原子与光腔，超导电路或限制光学访问的光学机械设备相结合。
We developed an ultra-compact high-resolution imaging system for cold atoms. Its only in-vacuum element is a multimode optical fiber with a diameter of $230\,μ$m, which simultaneously collects light and guides it out of the vacuum chamber. External adaptive optics allow us to image cold Rb atoms with a $\sim 1\,μ$m resolution over a $100 \times 100\,μ$m$^2$ field of view. These optics can be easily rearranged to switch between fast absorption imaging and high-sensitivity fluorescence imaging. This system is particularly suited for hybrid quantum engineering platforms where cold atoms are combined with optical cavities, superconducting circuits or optomechanical devices restricting the optical access.
