Enhanced Atomic Magnetometry with a Pinched Spin State
Tingxuan Guo, Xiangyu Li, Yang Li +1
The sensitivity of an atomic spin sensor is fundamentally constrained by the quantum Fisher information (QFI) of the probe state. The pinched state, , has an …
FID Magnetometer Based on Paraffin-Coated Planar Reflective Multipass Cells
Xiangyu Li, Tingxuan Guo, Yang Li +1
We demonstrate a paraffin-coated planar reflective multipass vapor cell for compact optical atomic magnetometry. The cell has an internal volume of $12 \times 12 \times 8~\mathrm{m…
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…
