Radiation source for helium magnetometers

, 1991
A radiation source (12) for optical magnetometers (10) which use helium isotopes as the resonance element (30) includes an electronically pumped semiconductor laser (12) which produces a single narrow line of radiation which is frequency stabilized to ...

Radio-Frequency Optically Pumped Magnetometers for Eddy Current Measurements [PDF]

Radio-frequency optically pumped magnetometers (RF OPMs) are capable of measuring oscillating magnetic fields with high sensitivity in the fT/sqrt(Hz) range. Two types of RF OPMs are presented in this thesis. The first is a portable, orientation-based RF
