Magnetometry based on nonlinear magneto-optical rotation with amplitude-modulated light

Nonlinear magneto-optical rotation (NMOR), an all-optical technique now finding its use in sensitive magnetometry, is light-intensity-dependent rotation of the polarization plane of linearly polarized light upon its propagation through a medium placed in a magnetic field. NMOR technique enables measurements of magnetic field from 0 to 50 muT with the expected sensitivity of 10-14 T Hz-1/2.

Room temperature femtotesla radio-frequency atomic magnetometer

A radio-frequency tunable atomic magnetometer with a sensitivity of about 1 fT/Hz1/2 in a range of 10–500 kHz is demonstrated. The magnetometer is operated in the orientation configuration in which atoms are pumped to the stretched atomic state by a scheme based on indirect optical pumping using only one unmodulated, low-power laser. The magnetometer operates with cesium atoms, which have sufficient vapor pressure near room temperature to enable high magnetometric sensitivities. The technique enables a compact and robust module to be constructed that could become an in-the-field device.
