We demonstrate a movable, Rydberg atom-based radio frequency (RF) electric (E) field probe. The technique is based on electromagnetically induced transparency and Autler-Townes splitting. Two fibers attached to a 10 mm cubic Cs133 vapor cell are used to couple counter-propagating probe and control lasers through the cell. This all-dielectric fiber-coupled sensor can be moved from the optics table to locations more suitable for RF (gigahertz to sub-terahertz) E-field measurements and calibrations.
我们展示了一种基于里德堡原子的可移动射频（RF）电场（E）探头。该技术基于电磁诱导透明和奥特勒-汤斯分裂。两根连接到一个10毫米立方体Cs133蒸气室的光纤用于通过该室耦合反向传播的探测激光和控制激光。这种全介质光纤耦合传感器可以从光学平台移动到更适合进行射频（吉赫兹到亚太赫兹）电场测量和校准的位置。
