Abstract: A color dazzle system to enhance area denial to personnel mission for law enforcement, homeland security, border patrol, and the military effectively by interrupting the ability of combatants to continue with their intended mission. The color dazzle system has a multi-wavelength laser module for generate desired color or wavelength ranges of light, a beam projector module for pointing the light towards the target to be dazzled, and a fiber optic beam delivery system for delivering the light to the beam projector module. By adjusting the power output according to the corresponding wavelength and the distance to the target, and quickly switching between the wavelengths of light, a dazzle effect can be obtained with an irradiance within a safety range for the eye.

Abstract: A ring laser gyro, having: an envelope for an optically resonant cavity having a gain bore section, the envelope containing an active gas medium. The envelope contains electrically energizable electrode means having at least two electrodes at electrode locations within the envelope for establishing an electrical discharge in an active gas medium between the electrode locations. The electrical discharge excites a pair of light beams along a lasting path between the electrode locations. The light beams counterpropagate in the optically resonant cavity. The envelope is coupled to means for generating an output signal for the gyro by measuring a difference in the frequencies of the light beams. The active gas medium has an axial current driven gas flow and a return gas flow induced by the electrical discharge, the resultant gas flow contributing to bias errors in the output signal. The envelope also comprises a gas bypass cavity adapted to pneumatically couple the electrode locations along the gain bore.

The envelope contains electrically gain bore energizable electrode means having at least two electrodes at electrode locations within the envelope for establishing an electrical discharge in an active gas medium between the electrode locations. The electrical discharge excites a pair of light beams along a lasing path between the electrode locations. The light beams counter-propagate in the optically resonant cavity. The envelope is coupled to means for generating an output signal for the gyro by measuring a difference in the frequencies of the light beams. The active gas medium has an axial current driven gas flow and a return gas flow induced by the electrical discharge in the gain bore. The resultant gas flow contributes to bias errors in the output signal.

Abstract: A ring laser gyroscope incorporates a resonant cavity generally shaped as an irregular pentagon having a portion thereof conformed as three legs of a rectangle closed by two symmetrical other legs to form an apex. As result the enclosed area is increased, increasing sensitivity and decreasing lock-in, while magnetic effects are reduced. Additionally, the irregular shape allows for the extension of the gain medium which therefore increases the effectiveness thereof.

Abstract: Apparatus for generating a high-energy temporally shaped, coherent series of laser pulses having signal components on pre-selected rotational vibrational transitions, comprising: a waveguide laser array having an output comprising a desired temporally shaped coherent series of laser pulses on one pre-selected rotational vibrational transition, a second-harmonic generator arranged to double the waveguide laser array output frequency, a line matching laser array having a plurality of outputs of another temporal shape on additional rotational vibrational transitions, and means comprising an array of difference frequency mixers responsive to synchronized reception of line matching laser array outputs and said frequency doubled waveguide laser array output to form a corresponding high-energy, coherent series of laser pulses having a waveguide laser array output-determined temporal shape and line matching laser array output-determined rotational vibrational transitions.
