  • Polarization based mode-locking of a laser
    Patent number: 6021140
    Abstract: The present invention is a system and method for mode-locking a laser, comprising reversibly converting radiation in the laser at a fundamental frequency into radiation at a second harmonic frequency, discriminating the radiation at the fundamental frequency using a polarization of the radiation at the fundamental frequency, and reconverting the radiation at the second harmonic frequency into radiation at the fundamental frequency.

  • Device for shaping the angular response of a light meter or the angular emission of a light source
    Patent number: 4729655
    Abstract: A fiber optic (12) and correcting element (18) combination with the property of providing shaped angular response when used in conjunction with a radiometer, and of providing shaped angular emission when used in conjunction with a light source.

  • Rapid scanning autocorrelation detector
    Patent number: 4406542
    Abstract: Autocorrelation traces of laser pulses of short duration are produced by a method and apparatus that uses a rotating glass block to vary the path length on a time scale rapid enough to display the traces on a synchronized oscilloscope. Both paths of a split input beam of a laser pulse pass through the glass block. Rotation of the glass block changes the relative time of travel for light pulses along the two paths. The paths of the two beam arms pass through the block from different directions at a relative angle chosen so that the relative travel time difference is nearly linearly related to the angular position of the block during its rotation.Autocorrelation with rapid scanning through rotation of the block enables measurement of repetitive laser light pulses of very short duration, down to the order of one picosecond.
