Development and characterization of a single-beam optically pumped magnetometer out of mass-producible components

Magnetic field detection based on optically pumped alkali-atom vapors is an attractive and potentially clinically translatable technology for biomagnetism studies, e.g. magnetoencephalography. In this work, we report on the development and characterization of a prototype, single-beam zero-field-reso...

Sumario:Magnetic field detection based on optically pumped alkali-atom vapors is an attractive and potentially clinically translatable technology for biomagnetism studies, e.g. magnetoencephalography. In this work, we report on the development and characterization of a prototype, single-beam zero-field-resonance (ZFR) magnetometer developed out of inexpensive miniaturized components, avaliable through mass-production. Using a tabletop setup, we report a magnetic sensitivity of about 15 fT/Hz^1/2, similar to that of commercially available sensors. We also experimentally obtain the number density of the rubidium-87 vapor cell at high temperatures.
