Optimization and vectorization of a Mz-type optically-pumped Rubidium magnetometer
Zhengyu Su, Yang Li, Yongbiao Yang +3
Optically pumped magnetometers (OPMs) have demonstrated significant potential in weak magnetic field detection due to their high sensitivity. In this study, we developed an Mz-type…
The Bell-Bloom-type optically-pumped FID Rubidium atomic magnetometer with a multi-passing probe beam and two counter-propagating pump beams
Yongbiao Yang, Zhengyu Su, Yang Li +4
The Bell-Bloom-type optically pumped atomic magnetometers are well suited for weak geomagnetic field detection. However, conventional single-beam pumping introduces an atomic spin…
Comparison and analysis of methods for measuring the spin transverse relaxation time of rubidium atomic vapor
Lulu Zhang, Ni Zhao, Yongbiao Yang +3
The spin transverse relaxation time (T_2) of atoms is an important indicator for precision measurement. Several methods have been proposed to characterize the T_2 of atoms. In this…
Measuring magnetic field coil constants based on atomic magnetometry and fluxgate magnetometry
Ni Zhao, Lulu Zhang, Yongbiao Yang +3
In a magnetic field detection system,to achieve high-sensitivity magnetic field measurement, it is necessary to use uniform magnetic field coils to provide a stable working environ…
