  • Isotropic and all-optical scalar magnetometer for measuring an ambient magnetic field
    Patent number: 11143722
    Abstract: An optical-pumping magnetometer intended to measure an ambient magnetic field.
    Type: Grant
    Filed: February 26, 2020
    Date of Patent: October 12, 2021
    Assignee: COMMISSARIAT À L'ÉNERGIE ATOMIQUE ET AUX ÉNERGIES ALTERNATIVES
    Inventors: Gaëtan Lieb, Agustin Palacios Laloy
  • Vector magnetometer in alignment with two differently polarised probe beams
    Patent number: 11054489
    Abstract: A vector magnetometer comprises a cell to be filled with an atomic gas, an optical source and a photo-detection device. The optical source is configured to emit towards the cell: a first and a second optical beam, called probe beams, that are polarised linearly, a third optical beam, called the pump beam, linearly polarised. The polarisation directions of the probe beams and the polarisation direction of the pump beam are not coplanar. The photo-detection device is configured to receive light from the probe beams that have passed through the cell. The probe beams can have the same propagation direction. The polarisation direction of the pump beam can form an angle of 45°±10° with the polarisation direction of each of the probe beams.
