摘要:

基于线偏振双色场中原子与光相互作用的对称性和高对比度EIT共振态,提出了EIT矢量磁强计的一般原理。并演示了这种矢量磁力仪在~(87)Rb D_1线上的工作。建议的指南针磁力计有一个增加的免疫力所产生的位移二次塞曼和交流斯塔克效应,以及原子缓冲气体和原子原子碰撞。在我们的原理验证实验中,检测到的对磁场方向的灵敏度为10^{-3} deg/Hz^{1/2},这受到激光强度波动、光偏振质量和磁场大小的限制。

英文摘要:

We develop a generalized principle of EIT vector magnetometry based on high-contrast EIT-resonances and the symmetry of atom-light interaction in the linearly polarized bichromatic fields. Operation of such vector magnetometer on the D1 line of 87Rb has been demonstrated. The proposed compass-magnetometer has an increased immunity to shifts produced by quadratic Zeeman and ac-Stark effects, as well as by atom-buffer gas and atom-atom collisions. In our proof-of-principle experiment the detected sensitivity to magnetic field orientation is 10^{-3} deg/Hz^{1/2}, which is limited by laser intensity fluctuations, light polarization quality, and the magnitude of the magnetic field.
