摘要：

In this work, a single-laser-beam-based atomic Faraday-rotation magnetometer (FRM) scheme is studied in which atoms interact with a triple-chromatic laser beam. The circularly polarized carrier component of the beam prepares the atoms while its two orthogonal linearly polarized +/- 1st sidebands are rotated oppositely and then measured. The study result reveals that the FRM scheme is suitable for implementation of a compact sensor supported by a fiber-coupled laser and is also suitable for implementation of a chip-scale sensor with a self-contained light source when using microelectromechanical systems (MEMS) technology.
