The Effects of Pump Beam on Cesium Magnetometer Sensitivity

Abstract:

This paper described an all-optical cesium atomic magnetometer whose measuring sensitivity achieves 0.3pT/Hz1/2. In order to achieve high measuring sensitivity, the dominant parameter, a circularly polarized pumping laser which is used to polarize the cesium atoms was well discussed. After a series of experimental tests, the relationships between the output signals based on absorptive detection with pump beam were expressed here. When the optical pumping frequency was stabilized to the center of the resonance line Fg =3→Fe=4 of the cesium D1 transition, it was found that the optimum pump beam intensity was 6 mW/cm2 for this kind of magnetometer to achieve its highest sensitivity.
