Applications of multipass cells in atomic magnetometers and co-magnetometers.

Multipass cells help to improve the magnetometer sensitivity while keeping the small size of the device. By combining anodic bonding and mechanical mold assisted positioning, we developed a way to produce standardized atomic vapor cells containing Herriott multipass cavities, which are used together with 3D printed platforms without the need of optical adjustments. We applied such cells in the Xe isotopes-Rb co-magnetometer system to improve the Rb magnetometer sensitivity. We further developed a three-mirror Herriott cell, and applied it in vector atomic magnetometers.
