  • Optical wedges used in beam expander for divergence control of laser
    Patent number: 4846550
    Abstract: Laser beam divergence control is achieved by interposing a pair of optical wedges (41,42) in the beampath of a laser between a pair of lenses (33, 35) of a beam expander (31). The expanded beam has a reduced tendency to jitter during divergence control and the wedges (41, 42) cause a change in divergence by adjusting the optical separation of the lenses (33, 35). By the use of wedges (41, 42) optical length adjustments do not significantly affect directional stability of the beampath.

  • Covert recovery or signalling system
    Patent number: 4203667
    Abstract: A signalling system for downed aircrew recovery. The system uses an infra laser beam aimed at a search aircraft which has a detector and a position indicator to locate the transmitter so that the downed crew may be rescued.

  • Common aperture laser transmitter/receiver
    Patent number: 4025194
    Abstract: A common-optics laser transceiver has a common aperture for transmitting receiving a laser beam, and uses the resonator polarizer to separate the resonator beam from the receiver beam, resulting in a polarization sensitive, lightweight laser transmitter/receiver.

  • Tunable electroabsorptive detector
    Patent number: 3976873
    Abstract: A tunable, electroabsorptive, semiconductor detector or detector-modulator for detecting or modulating radiation near the absorptive edge of the detector, which edge can be tunably shifted by back biasing.
