Latest Patents
Cort N Johnson holds a patent for an atomic magnetometer. This device utilizes a pump light beam at a D1 or D2 transition of an alkali metal vapor to magnetically polarize the vapor within a heated cell. A probe light beam at a different D2 or D1 transition is then used to sense the magnetic field by observing the polarization rotation of the probe light beam. Both the pump and probe light beams are directed along substantially the same optical path through an optical waveplate and the heated cell. An optical filter blocks the pump light beam while allowing the probe light beam to pass through to one or more photodetectors, which generate electrical signals to sense the magnetic field. The optical waveplate serves dual functions, acting as a quarter waveplate to circularly polarize the pump light beam and as a half waveplate to maintain the probe light beam in a linear polarization state.
