摘要

Yb中的互组合跃迁为快速成像磁场变化提供了一种新颖的方法，具有优异的时空分辨率和精度。这种量子成像磁力计揭示了“暗条纹”，即肉眼可见或标准相机可以捕捉到的恒定磁场的轮廓。这些暗线是在多个强相干激光场（单模556nm激光的载波和AM/FM调制边带）驱动下，Yb的S01−P13跃迁中的Autler-Townes分裂和空间Hanle效应共同作用的结果。我们展示了封闭的4级塞曼位移V系统的实验数据与理论模型之间的良好一致性，并演示了在空间维度为5厘米、分辨率为0.1 mm的视频帧率下的标量和矢量磁场测量。此外，S01−P13跃迁允许~ μs的响应时间和大的动态范围（从微特斯拉到许多特斯拉）。2025年由美国物理学会出版

Quantum States Imaging of Magnetic Field Contours Based on Autler-Townes Effect in Ytterbium Atoms

An intercombination transition in Yb enables a novel approach for rapidly imaging magnetic field variations with excellent spatial and temporal resolution and accuracy. This quantum imaging magnetometer reveals “dark stripes” that are contours of constant magnetic field visible by eye or capturable by standard cameras. These dark lines result from a combination of Autler-Townes splitting and the spatial Hanle effect in the S01−P13 transition of Yb when driven by multiple strong coherent laser fields (carrier and AM/FM modulation sidebands of a single-mode 556 nm laser). We show good agreement between experimental data and our theoretical model for the closed, 4-level Zeeman shifted V system and demonstrate scalar and vector magnetic field measurements at video frame rates over spatial dimensions of 5 cm with 0.1 mm resolution. Additionally, the S01−P13 transition allows for ∼μs response time and a large dynamic range (from microtesla to many tesla).
