  • Quantum mechanical measurement device
    Patent number: 9726626
    Abstract: A quantum mechanical measurement device is provided. A spin ensemble is provided. A first light source provides a first light at a first wavelength, wherein the first light source is positioned to provide light into the spin ensemble. A detector is positioned to detect light from the spin ensemble. A modulator modulates absorption of the first light from the first light source by the spin ensemble at a frequency greater than a Larmor frequency of the spin ensemble.
    Type: Grant

    Inventors: Kenneth R. Smith, Krzysztof Kiersnowski
  • Optical magnetometers
    Patent number: 9726733
    Abstract: An optical magnetometer is disclosed. The device includes a cell filled with a substance that has a magnetic moment, such as an alkali metal. First and second light sources, typically diode lasers, illuminate the cell, one optically pumping the cell and one probing the cell. The two diode lasers are set to emit light at two distinct wavelengths, one set to drive a first transition and the other set to drive a second transition within the substance filling the cell. The probe laser light transiting the cell is used to modulate the frequency of the probe laser. The two beams of light are polarized with an ellipticity of at least 0.3.
