Patent number: 9575309Abstract: The present invention provides a reflective telescopic system, to control the generation of filamentation of ultrashort and intense laser pulses that includes: a flat mirror, an adaptive reflective mirror, a dichroic convex mirror, an off-axis parabolic mirror, and a first laser source. The convex mirror and the adaptive reflective mirror are mounted on an independent breadboard and set on a translation stage. The propagation axis of the laser beam reflected by the mirror should correspond to the off-axis of the parabolic mirror. The parabolic mirror reflects the beam at a specific angle. Finally, the propagation axis between the dichroic convex mirror and the off-axis parabolic mirror, the propagation axis between the flat mirror and the adaptive reflective mirror, and the axis of the translation stage should be substantially parallel to each other. The present invention also contemplates the boresighting of a weak laser beam from a second laser source.Type: GrantFiled: September 10, 2012Date of Patent: February 21, 2017Assignee: HER MAJESTY THE QUEEN IN RIGHT OF CANADA, AS REPRESENTED BY THE MINISTER OF NATIONAL DEFENCEInventors: Francis Théberge, Jacques Dubois, Marc Châteauneuf

Patent number: 9484702Abstract: A method comprising using a pulse shaper in the spectral domain to generate multiple-color pulses directly at the output of the laser amplifier. The delay can thus be controlled directly in the spectral domain and there is no need for an optical delay line. The method allows reducing the number of optical components and insures insensitivity to alignment, vibrations and turbulence on long distance propagation and filamentation, particularly in air. The method allows programmable and tunable interaction, since the pulse shaper is able to control the laser spectral amplitude and phase.Type: GrantFiled: March 23, 2012Date of Patent: November 1, 2016Assignee: INSTITUT NATIONAL DE LA RECHERCHE SCIENTIFIQUEInventors: Stéphane Payeur, Philippe Lassonde, Jean-Claude Kieffer, Francis Théberge, Marc Chàteauneuf, Jacques Dubois

Patent number: 7414568Abstract: A laser warning receiver (LWR) to detect a very low power laser beam for a laser beam rider and provide a high angular resolution in determining the angle-of-arrival of that beam. An aperture having a fixed field-of-view (FOV) is located in a detection channel followed by a narrow-band filter and a detector whose output is applied to a pulse analyzer circuit. A localization channel with the same FOV has a similar narrow-band filter and a lens to focus light from that FOV onto a detector through a N×M element LCD matrix, an output of that detector being applied to the pulse analyzer circuit whose output is applied to a LCD pattern selector connected to the matrix which controls elements in the matrix to provide a transparent window of variable size and position. The size and position of that window allows a laser beam to reach the detector, the window being iterative reduced in size when a beam is detected to provide the location of its source.Type: GrantFiled: March 25, 2003Date of Patent: August 19, 2008Assignee: Her Majesty the Queen in right of Canada, as represented by the Minister of National Defence of Her Majesty's Canadian GovernmentInventors: Jean Fortin, Jacques Dubois

Patent number: 7175130Abstract: A guidance system for a missile with a laser beam source located at a distance from the missile generating a modulated laser beam that is directed towards the missile. A group of backward looking sensors on the body of the missile detect any radiation scattered from the laser beam along with a group of forward looking sensors located on the missile. Both groups look at an angle to the missile's longitudinal axis. Signals from the sensors are applied to processing electronics in the missile that determine the phase shift in signals derived from when a backward looking sensor detects scattered radiation from a laser beam and a forward looking sensor detects scattered radiation from that beam. The processing electronics can then accurately determine the distance between the missile and the beam from the phase shift and correct the missile's trajectory to maintain its position with respect to the beam.Type: GrantFiled: September 3, 2004Date of Patent: February 13, 2007Assignee: Her Majesty the Queen in right of Canada, as represented by the Minister of National Defence of Her Majesty's Canadian GovernmentInventors: Jacques Dubois, Jean Fortin, Pierre Mathieu

Patent number: 7150428Abstract: A guidance system for a missile utilitizes a laser beam source at a missile launch pad to generate a laser beam that is directed towards a target. A sensor on the body of a spinning missile detects radiation scattered from the laser beam, the sensor looking sideways and backward at an angle to the missile's longitudinal axis. Signals generated by that sensor are applied to a missile's guidance system's processing electronics that then determines the distance from the missile to the beam from the width of the signal generated by the sensor due to detecting scattered radiation from that laser beam. Once the distance between the missile and the beam is determined, the missile's guidance system corrects the missile's trajectory to maintain its position at a predetermined distance from the beam.Type: GrantFiled: September 3, 2004Date of Patent: December 19, 2006Assignee: Her Majesty the Queen in right of Canada, as represented by the Minister of National DefenceInventors: Jacques Dubois, Jean Fortin
