Stray Magnetic Field Compensation with a Scalar Atomic Magnetometer

, 2010
We describe a system for the compensation of time-dependent stray magnetic fields using a dual channel scalar magnetometer based on non-linear Faraday rotation in synchronously optically pumped Cs vapour.

Electromagnetic induction imaging with atomic magnetometers [PDF]

Quantum Information and Measurement (QIM) V: Quantum Technologies, 2017
We report on the development and performance of an electromagnetic induction imaging system based on atomic magnetometers.We discuss, and demonstrate experimentally, potential applications of our system in the security, industrial, and biomedical fields.

Far Off-Resonance Laser Frequency Stabilization Technology

Applied Sciences, 2020
In atomic physics experiments, a frequency-stabilized or ‘locked’ laser source is commonly required. Many established techniques are available for locking close to an atomic resonance.

Microtesla NMR J-coupling spectroscopy with an unshielded atomic magnetometer

, 2016
We present experimental data and theoretical interpretation of NMR spectra of remotely magnetized samples, detected in an unshielded environment by means of a differential atomic magnetometer.

AC Stark shift noise in QND measurement arising from quantum fluctuations of light polarization

, 2004
In a recent letter [Auzinsh {\it{et. al.}} (physics/0403097)] we have analyzed the noise properties of an idealized atomic magnetometer that utilizes spin squeezing induced by a continuous quantum nondemolition measurement.

Isotropic magnetometry with simultaneous excitation of orientation and alignment CPT resonances

, 2010
Atomic magnetometers have very high absolute precision and sensitivity to magnetic fields but suffer from a fundamental problem: the vectorial or tensorial interaction of light with atoms leads to "dead zones", certain orientations of magnetic field ...

Spin damping in an rf atomic magnetometer

Physical Review A, 2013
Under negative feedback, the quality factor Q of a radio-frequency magnetometer can be decreased by more than two orders of magnitude, so that any initial perturbation of the polarized spin system can be rapidly damped, preparing the magnetometer for detection of the desired signal.
