Publication number: 20100316072Abstract: Methods stabilize the output of a pulsed laser system using pulse shaping capabilities. In some embodiments, transient effects following a transition between a QCW regime and a pulse shaping regime are mitigated by ensuring that the average QCW optical power substantially corresponds to the average pulsed optical power outputted in a steady-state operation of the pulsed laser system in the pulse shaping regime. The QCW signal or the pulse shaping signal may be adapted for this purpose. In other embodiments, transient effects associated with non-process pulses emitted between series of consecutive process pulses are mitigated through the proper use of sequential pulse shaping.Type: ApplicationFiled: May 18, 2010Publication date: December 16, 2010Applicant: Institut National D'OptiqueInventors: Pascal Deladurantaye, Louis Desbiens, Yves Taillon, Dany Lemieux, Brian W.

Publication number: 20100135347Abstract: A method and device are provided for generating bursts of sub-pulses, preferably in the picosecond range. Seed pulses are first generated, and then phase modulated to spread their spectral profile to several time-dependent spectral components. The phase modulated seed pulses are then spectrally filtered to remove spectral components and retain only selected ones, creating gaps in the amplitude profile of the seed pulses which therefore form bursts of sub-pulses. Various parameters such as the modulation amplitude, the modulation frequency, the spectral characteristics of the filters and the overall amplitude of the seed pulses may be controlled to provide a great versatility and adaptability.Type: ApplicationFiled: November 23, 2009Publication date: June 3, 2010Applicant: Institut National D'OptiqueInventors: Pascal Deladurantaye, Louis Desbiens, Vincent Roy, Yves Taillon

Publication number: 20100128744Abstract: High power optical pulses generating methods and laser oscillators are provided. A light generating module generates seed optical pulses having predetermined optical characteristics. A spectrum tailoring module is then used to tailor the spectral profile of the optical pulses. The spectral tailoring module includes a phase modulator which imposes a time-dependent phase variation on the optical pulses. The activation of the phase modulator is synchronized with the passage of the optical pulse therethough, thereby efficiently reducing the RF power necessary to operate the device.Type: ApplicationFiled: March 20, 2009Publication date: May 27, 2010Applicant: Institut National D'OptiqueInventors: Pascal Deladurantaye, Louis Desbiens, Marco Michele Sisto, Mathieu Drolet, Vincent Roy, Yves Taillon

Publication number: 20100040098Abstract: A laser diode illuminator device and a method for optically conditioning the output beam radiated from such a device, so that highly-demanding illumination application requirements that call for high output powers within a specified field of illumination can be addressed. At the heart of the device is a two-dimensional stack of laser diode bars wherein the linear array of beamlets radiated by each laser diode bar is optically conditioned through its passage in a refractive-type micro-optics device followed by a cylindrical microlens. The micro-optics device performs collimation of the linear array of beamlets along the fast axis of the bars, and it also acts as a beam symmetrization device by interchanging the divergences of the laser beamlets along the fast and slow axes. The cylindrical microlens is for collimation of the beamlets along the slow axis.Type: ApplicationFiled: March 10, 2009Publication date: February 18, 2010Applicant: Institut National D'OptiqueInventors: Andre Parent, Paul Grenier, Yves Taillon, Bruno Labranche

Publication number: 20090323741Abstract: A digital pulse shaping module for controlling a pulsed laser oscillator according to a digital input waveform is provided. The pulse shaping module includes a clock generator generating a plurality of phase-related clock signals and a shape generator which outputs a digital shape signal corresponding to the digital input waveform in Double Data Rate in response to the clock signals. A DAC converts the digital shape into an analog shape signal. The analog shape signal may be used to control the current source of a laser seed source or modulators in the laser oscillator shaping a seed light signal. Optionally, the pulse shaping module may also output a gate control signal having a predetermined timing relationship with respect to the digital shape signal.Type: ApplicationFiled: June 29, 2009Publication date: December 31, 2009Applicant: Institut National D'OptiqueInventors: Pascal Deladurantaye, François Duchesne, Michel Jacob, Yvan Mimeault, André Parent, Yves Taillon

Publication number: 20050068633Abstract: Apparatus for shaping an optical beam bundle carrying a plurality of substantially parallel optical beams disposed in a common plane of travel. First reflective facets and second reflective facets are provided, the first reflective facets being oriented so as to deflect the optical beams of the bundle into a plurality of intermediate, substantially non-parallel optical beams. Each of the second reflective facets is spatially disposed so as to receive a respective one of the intermediate optical beams at a different respective distance from the plane of travel of the optical beam bundle. Also, the second reflective facets are oriented so as to deflect the intermediate optical beams into a bundle of substantially parallel output optical beams. In this way, the output beam can be more adapted for a particular application. In certain cases, this also achieves increased brightness of a laser beam through reduced output beam divergence and/or total cross-sectional area.Type: ApplicationFiled: September 30, 2003Publication date: March 31, 2005Inventors: Paul Grenier, Yves Taillon
