Alleviating optical pumping inhomogeneity using a polarization-encoded metasurface in NMR co-magnetometers [PDF]
Microsystems & NanoengineeringIn nuclear magnetic resonance (NMR) co-magnetometers, the non-uniform transverse energy distribution of the pumping Gaussian beam can result in substantial optical pumping inhomogeneity and decoherence of atomic spins, which hinder the improvement of the

Analysis and Correction of the Crosstalk Effect in a Three-Axis SERF Atomic Magnetometer
Photonics, 2022 Three-axis atomic magnetometers have an excellent advantage for determining the complete vector information of a magnetic field to be measured. However, the crosstalk effect, which leads to an error output on one axis owing to a magnetic field on the ...

Measuring huge magnetic fields [PDF]
Nature, 2002 Huge magnetic fields are predicted to exist in the high-density region of plasmas produced during intense laser-matter interaction, near the critical-density surface where most laser absorption occurs, but until now these fields have never been measured.

Magnetic Field Measurements for Fast-Changing Magnetic Fields [PDF]
IEEE Transactions on Appiled Superconductivity, 2005 Several recent applications for fast ramped magnets have been found that require rapid measurement of the field quality during the ramp. (In one instance, accelerator dipoles will be ramped at 1 T/sec, with measurements needed to the accuracy typically required for accelerators.) We have built and tested a new type of magnetic field measuring system to

On-Chip Mach-Zehnder-Like Interferometer for Atomic Spin Precession Detection
IEEE Photonics Journal, 2023 At present, most atomic spin precession detection schemes use discrete optical elements, which lead to bulky detection systems. However, chip-based spin precession detection schemes lack modulation, resulting in lower detection sensitivity. In this paper,
