  • Four-wave mixing source of squeezed light for image processing and interferometry
    Patent number: 7453626
    Abstract: A four-wave mixing squeezed light source includes: a mixing medium having chi(3) non-linear characteristics including two atomic ground states coupled to each other by transitions through optically-excited states; a pump beam having a polarization and a frequency, said frequency being near the ground-to-excited atomic transition but far enough from the atomic transition such that the pump beam is substantially unabsorbed; and a probe beam having a polarization that is orthogonal with respect to the pump beam polarization, the probe beam having a frequency of the pump beam frequency plus or minus a frequency splitting of the two atomic ground states. The mixing medium, the pump beam and the probe beam interact to produce a phase conjugate beam having a polarization that is orthogonal to the pump beam polarization, such that the beams are non-degenerate with the pump beam, and the probe beam is amplified.
    Type: Grant

  • Electromagnetic device for production of cold neutral atoms
    Patent number: 6548809
    Abstract: An electromagnetic device for producing cold neutral atoms having a ferromagnetic structure with four poles disposed in the same plane XOY excited by main coils (the quadrupole) supplying the main excitation, and two additional poles (the dipole) oriented along an axis Z and perpendicular to the plane of said four poles, the poles being magnetically coupled by one or more yokes.
