  • Gated image intensifiers for active imaging of reflectors by day or night
    Patent number: 5408099
    Abstract: Lightweight low power IR locater for reflection enhanced targets with .apeq.20 microsecond pulsed IR diode laser and 26 40 microsecond synchronized range-gated image.
    Type: Grant
    Filed: September 7, 1993
    Date of Patent: April 18, 1995
    Assignee: The United States of America as represented by the Secretary of the Army
    Inventors: Dallas N. Barr, John E. Nettleton, Brian C. Redman, Clifton S. Fox
  • Stabilized reference surface for laser vibration sensors
    Patent number: 4777825
    Abstract: The invention provides a vibration sensor with a platform mounted Bragg c frequency shifter and heterodyne detection system, wherein the reference beam is modulated with the component of platform vibration normal to the sensing beam, such that a similar modulation of the sensing beam is cancelled by the heterodyning process.
    Type: Grant
    Filed: July 15, 1987
    Date of Patent: October 18, 1988
    Assignee: The United States of America as represented by the Secretary of the Army
    Inventors: Dallas N. Barr, Clifton S. Fox, John E. Nettleton
  • Double helix RF line for CO.sub.2 laser
    Patent number: 4759028
    Abstract: A novel design for an RF pumped gas laser is provided by spiralling an RF in lead transmission line around a ceramic gas container. The pitch of the spiral and spacing between the leads of the transmission line are chosen to produce currents parallel to the axis of the spiral to provide more efficient energy transfer modes between the pump and the lasing gas.

    Inventors: John E. Nettleton, Dallas N. Barr, Clifton S. Fox
  • Transverse ring RF line for CO.sub.2 laser
    Patent number: 4689798
    Abstract: A far-infrared laser structure is provided wherein a uniform longitudinal ectric field mode is provided for a radio frequency pump by means of a set of fully or near-fully circular ring shaped electrodes.
    Type: Grant
    Filed: July 31, 1986
    Date of Patent: August 25, 1987
    Assignee: The United States of America as represented by the Secretary of the Army
    Inventors: Clifton S. Fox, John E. Nettleton, Dallas N. Barr
  • High efficiency transversely excited electrodeless gas lasers
    Patent number: 4359777
    Abstract: A high efficiency gas laser which utilizes transverse electrical excitation f a laser gas medium confined in a circular cylindrical volume. Limitation of the excitation energy to only the optical mode volume of the laser eliminates the inefficiency associated with conventional TEA laser technology in which a much larger gas volume is excited for a given optical mode volume. The present invention is comprised of a new design making possible the higher efficiencies through use of dielectric coupling between concave electrodes.
    Type: Grant
    Filed: January 22, 1981
    Date of Patent: November 16, 1982
    Assignee: The United States of America as represented by the Secretary of the Army
    Inventors: Clifton S. Fox, Jay A. Fox, Dallas N. Barr
  • Multiple-section pulsed gas laser
    Patent number: H882
    Abstract: Several gas-tight enclosures share a common optical cavity. The enclosures may be filled with neat gases or mixtures of gasses. The same gas or mixture, at the same or a different pressure, may occur in more than one enclosure. The gas or gasses in the various enclosures may be pulsed to lase in any desired sequence, simultaneously, or in any combination.
