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 ...

Single-light-source three-axis atomic magnetometer based on orthogonal and non-overlapping dual-pump beams

Results in Physics, 2023
In this paper, we propose a three-axis atomic magnetometer (AM), in which one light beam is divided into two orthogonal spatially separated pump beams by a lateral displacement polarized beam splitter and reflector mirrors; this scheme suppresses the ...
