Triaxial closed-loop measurement based on a single-beam zero-field optically pumped magnetometer

Frontiers in Physics, 2022
In this study, we propose an approach for the simultaneous measurement of triaxial magnetic fields using a single-beam zero-field optically pumped atomic magnetometer, in which a rotational high-frequency (ω1) and another high-frequency (ω2) modulated ...

Comprehensive analysis of the influence of magnetic field gradients on single-beam SERF atomic magnetometer

Results in Physics
Magnetic field gradients interfere with the coherence of the atomic ensemble and degrade the performance of the spin-exchange relaxation-free (SERF) atomic magnetometer.

A Compact Laser Pumped ⁴He Magnetometer with Laser-Frequency Stabilization by Inhomogeneous Light Shifts

Applied Sciences, 2020
We propose a compact 4He magnetometer realizing magnetic field measurement and laser-frequency stabilization simultaneously in a single 4He atomic cell. The frequency stabilization scheme is based on the asymmetric line shape of magnetic resonance which ...

Design of a Laser Frequency Stabilization for Cs Atomic Magnetometer

, 2017
An atomic magnetometer can measure weak magnetic fields with a high sensitivity $\sim~fT/\sqrt{\textrm{Hz}}$, which can be reached with a laser stabilization technique. This sensitivity can be used in axion-like field search.
