  • Optical reflective diffraction device having a high resistance to laser flux
    Patent number: 9671534
    Abstract: The present invention relates to an optical device for reflective diffraction with high diffraction efficiency and high laser flux resistance. The device includes a protective structure having at least one mixture layer produced by a uniform mixture of a first material and of a second material, where both of these are dielectric, and wherein said first material has an optical index lower than that of the said second material.
    Type: Grant
    Filed: February 20, 2013
    Date of Patent: June 6, 2017
    Assignees: COMMISSARIAT A L'ENERGIE ATOMIQUE ET AUX ENERGIES ALTERNATIVES, CENTRE NATIONAL DE LA RECHERCHE SCIENTIFIQUE
