Total-field atomic magnetometry using an elliptically-polarized frequency-modulated light beam for geomagnetic-field applications

We investigate an all-optical scheme for high-sensitivity measurements of the Earth's scale magnetic field ($B$). The scheme is based on the Bell-Bloom technique with frequency-modulated light. A single elliptically polarized light beam is used both for pumping the alkali-metal atoms and probing Larmor precession of th...
