  • Patent number: 8798108
    Abstract: An embodiment relates to a device for generating a short duration laser pulse, which comprises: means for generating a laser beam and for filtering same, arranged in such a way as to generate an input laser beam providing an input laser pulse; a transparent slide comprising a non-linear scattering material; the laser generation means being arranged so that the slide widens the spectrum of the input laser pulse by phase self-modulation in order to generate a wide-spectrum laser pulse; compression means adapted for compressing the wide-spectrum laser pulse in order to generate a short duration laser pulse; wherein the laser generation means are arranged so that the input beam is spatially uniform on the transparent slide and has a break integral B lower than three when the input beam passes through the transparent slide.

  • Patent number: 8774240
    Abstract: A frequency-drift amplification device for a pulsed laser, including: a stretcher for time-stretching an incident laser pulse; at least one amplifying medium for amplifying the laser pulse; a main compressor for time-compressing the laser pulse to a desired duration for an output pulse of the amplification device; and at least one adjustment compressor between the stretcher and the main compressor, and in which the laser pulse undergoes four diffractions on diffraction gratings to time-compress the stretched laser pulse to a duration that is greater than the desired duration for the output pulse of the amplification device.

  • Publication number: 20130208740
    Abstract: An amplification device with frequency drift for a pulsed laser includes a stretcher temporally stretching an incident laser pulse, at least one amplifying medium for amplifying the stretched laser pulse, and a compressor for temporally compressing the stretched and amplified laser pulse. The compressor includes an amplifying medium for amplifying a partially temporally compressed laser pulse, increasing energy yield of the amplifier.

  • Patent number: 7430351
    Abstract: The invention relates to a non-linear optical filter capable of transmitting an electromagnetic pulse with a duration of less than about 1 picosecond, provided with means for generating an electromagnetic field E with a linear polarization from this pulse, and with a crystal C1 of cubic geometry capable of generating an electromagnetic field E?1 from E with a linear polarization orthogonal to that of E. It comprises means for generating at least one other electromagnetic field E?2 capable of producing constructive interferences with the electromagnetic field E?1.
