  • Device for production of a polychromatic light over a continuous spectrum by excitation at one wavelength
    Patent number: 7800817
    Abstract: A device for producing a polychromatic light including an optical pump that delivers a first radiation at a first wavelength; a light guide; and a selective injector that injects the radiation into the guide, the guide being arranged to generate a harmonic corresponding to the selected injector and provide a polychromatic light at an outlet, by non-linear excitation of the first radiation and the harmonic.
    Type: Grant
    Filed: April 14, 2006
    Date of Patent: September 21, 2010
    Assignees: Centre National de la Recherche Scientifique-CNRS, Universite de Limoges
    Inventors: Vincent Couderc, Philippe Leproux, Vincent Tombelaine, Pierre-Alain Champert, Sébastien Février, Alain Barthélémy, Jean-Louis Auguste, Jean-Marc Blondy
  • Device for generating polychromatic light with a continuous spectrum
    Patent number: 7768691
    Abstract: A dedicated polychromatic light generating device including optical pumping devices used to deliver radiation with at least two different excitation wavelengths and a light-guiding device used to deliver polychromatic light at an output when excited by the radiation in a non-linear interaction regime.
