  • Method and laser oscillator for the generation of a laser beam
    Patent number: 9166359
    Abstract: Method and laser oscillator for the generation of a laser beam—According to the invention with a view to adjusting, inside said laser oscillator (1), the phase of each of the N elementary laser beams (FLE.1, FLE.2, FLE.N) generated on the basis of said laser oscillator (1) in such a way that said elementary laser beams are in phase, the deviation between the phase of an individual elementary laser beam (FLE.1) and the phases of the N?1 other elementary laser beams (FLE.2, FLE.N) is converted into a level of luminous intensity by means of at least one optical filtering element to which at least a part of each elementary laser beam is directed.
    Type: Grant
    Filed: November 29, 2011
    Date of Patent: October 20, 2015
    Assignee: COMPAGNIE INDUSTRIELLE DES LASERS CILAS
    Inventors: David Sabourdy, Jean-Eucher Montagne, Alain Barthelemy, Agnès Desfarges-Berthellemot, Vincent Kermene, Julien Guillot, Brigitte Serreault, Bruno Esmiller
  • Laser cavity with central extraction by polarisation for coherent coupling of intense intra-cavity beams
    Patent number: 8913645
    Abstract: The invention relates to a laser cavity with central extraction by polarisation for coherent coupling of intense intra-cavity beams. The laser cavity (1) according to the invention comprises an extraction unit (7) with central extraction, which divides the laser cavity (1) longitudinally into two functional portions (P1, P2), namely a first portion (P1) including the active components (3), which amplifies the laser beams (4), and a second portion (P2) which performs coherent coupling of the laser beams (4).
