摘要
A high-sensitivity radio-optical cesium magnetometer is designed and implemented. By studying the dependencies of the performance of the radio-optical cesium magnetometer on some related parameters, the optimal ranges of these parameters are obtained, and the magnetometer performance is optimized and tested. The test results show that the designed radio-optical cesium magnetometer can achieve a magnetometer sensitivity of 82.5 fT/root Hz, a resolution within 1 pT to an external magnetic field change, and a noise fluctuation of 0.2 pT for an integration time of 1 s.
