Unshielded scalar magnetometer based on nonlinear magneto-optical rotation with amplitude modulated light
In this article, a high-sensitivity magnetometer with paraffin-coated Cs vapor cell based on amplitude modulated nonlinear magneto-optical rotation (AM NMOR) is presented. The magnetometer has a wide dynamic range which covers the geomagnetic field range and its operation is demonstrated in an unshielded environment. The sensitivity of the magnetometer has reached sub-pT level. The main limitation to the resonance linewidth and the sensitivity is nonlinear Zeeman splitting.
