  • Atomic vapor laser isotope separation process
    Patent number: 4951287
    Abstract: A laser spectroscopy system is utilized in an atomic vapor laser isotope separation process. The system determines spectral components of an atomic vapor utilizing a laser heterodyne technique.
    Type: Grant
    Filed: June 15, 1988
    Date of Patent: August 21, 1990
    Inventors: Richard W. Wyeth, Jeffrey A. Paisner, Thomas Story
  • Heterodyne laser instantaneous frequency measurement system
    Patent number: 4940331
    Abstract: A heterodyne laser instantaneous frequency measurement system is disclosed. The system utilizes heterodyning of a pulsed laser beam with a continuous wave laser beam to form a beat signal. The beat signal is processed by a controller or computer which determines both the average frequency of the laser pulse and any changes or chirp of the frequency during the pulse.
    Type: Grant

  • Optical frequency doubler using electro-optic crystal with improved feedback control of crystal phase match
    Patent number: 4019159
    Abstract: An optical frequency doubling arrangement is disclosed in which the indices of refraction of light in a frequency doubling electro-optic crystal are controlled by both electric field pulses applied across the crystal and heater control pulses for controlling the temperature of an oven in which the crystal is mounted. Both the electric field pulses and the heater control pulses have a duty cycle determined by the detected optical power output from the crystal at the desired double frequency, the heater control pulses being responsive to the measured oven temperature as well. The arrangement is especially suitable for doubling the frequency of 1.06 .mu.m laser beams.
