Magnetometers based on Electromagnetically Induced Transparency (EIT) have shown the capability of vector and scalar measurements of magnetic fields in an all-optical interrogation scheme [1, 2]. The magnetic field strength is derived from a relative frequency shift of the atomic resonances proportional to its magnitude, with a scaling factor that depends only on fundamental constants of...

Detection dead-zones are important systematic effects in scalar atomic magnetometers, which limit their practical applications. In this work, we demonstrate a sensitive dead-zone-free scalar magnetometer by applying previously developed techniques in a FID magnetometer [1,2]. The detection dead zones are eliminated by adding a reflecting mirror in the middle of a multipass-cavity-assisted cell...

The emergence of Spin-Exchange-Relaxation-Free (SERF) Optically Pumped Magnetometers (OPMs), ranging from single-sensors to fully integrated multichannel systems, has opened new frontiers in biomedical applications and other sensing areas through remote and rapid magnetic field sensing. Without detailed manufacturer specifications, treating these sensors as black boxes can conceal critical...

Optically Pumped magnetometers (OPMs) have seen recent advances due to the emergence of new interrogation schemes, operational modalities, and availability of improved components forming the sensors. The use of microfabrication techniques for manufacturing alkali vapour cells [1,2], miniature optics and the integration of chip-scale lasers, allows for mass-production of compact, high...

The investigation of magnetic-resonance linewidth is of fundamental importance in the field of magnetic-resonance physics and its diverse applications. Previous research has predominantly focused on the linewidth of alkali metal atoms within two distinct regimes: the spin-exchange relaxation-free (SERF) regime near zero magnetic field, and strong magnetic fields where Zeeman resonances are...

Vector magnetometers provide lots of information for applications that require analysis of magnetic source ranging from bio-imaging to geophysical exploration. Magnetometer based on nitrogen-vacancy (NV) centers in diamond, as an unprecedented combination of spatial resolution and magnetic sensitivity, however, normally need complex manipulation to distinguish the correspondence between field...
