  • Injected laser and method for generating longitudinal multimode laser pulses
    Patent number: 10476225
    Abstract: Disclosed is an injected laser including an optical amplifying medium arranged inside a triggered laser cavity, the optical amplifying medium having a spectral amplifying band. The injected laser includes an optical phase-modulation device, arranged between the injection source and the laser cavity, the optical phase-modulation device being configured to periodically modulate as a function of time a phase of the monochromatic continuous laser radiation at a modulation frequency equal to a natural integer multiple of the free spectral range of the laser cavity, so that the phase-modulated injection source generates a polychromatic injection radiation.
    Type: Grant

  • Spectrometer comprising a plurality of diffraction gratings
    Patent number: 9638577
    Abstract: A spectrometer including: a spectral dispersion mechanism of an initial light beam; and a photodetector. The spectral dispersion mechanism includes at least three reflective diffraction gratings parallel to consecutive sides of a convex polygon, arranged such that a portion of the initial light beam is diffracted once by each diffraction grating in turn and is diffracted at least a second time by at least one of the diffraction gratings.
