  • Treatment of crystals in order to avoid light-induced modifications of the refractive index
    Patent number: 7833345
    Abstract: A method for the treatment of a crystal, such as a lithium niobate crystal or lithium tantalate crystal, having nonlinear optical properties. The crystal comprises foreign atoms which bring about specific absorption of radiated light. The foreign atoms are transformed into a lower valent state by means of oxidation. Electrons, which are released during oxidation, are discharged from the crystal with the aid of an external power source.
    Type: Grant
    Filed: September 30, 2004
    Date of Patent: November 16, 2010
    Assignee: Deutsche Telekom AG
    Inventors: Karsten Buse, Matthias Falk, Konrad Peithmann
