  • Laser gain module and method for producing such a module
    Patent number: 8929413
    Abstract: According to one embodiment, the invention relates to a laser gain module (1) comprising: a laser rod (5) having a shaft and two optical interfaces (7, 9) facing each other, the rod (5) being used for longitudinal or quasi-longitudinal optical pumping; and a metal cooling body (3), at least one part of which is molded around the laser rod (5) in order to cover all of the surfaces other than the optical interfaces in such a way that the laser gain module (1) forms a solid body that cannot be disassembled at ambient temperature.
    Type: Grant
    Filed: December 14, 2011
    Date of Patent: January 6, 2015
    Assignees: Fibercryst, CNRS
    Inventors: Nicolas Aubry, Didier Perrodin, Julien Didierjean, Jean-Marie Fourmigue, François Balembois, Igor Martial

  • X-ray scanning tube with deflecting plates
    Patent number: 5125019
    Abstract: In an x-ray tube of the beam deflection type for a radiology apparatus, the stair-steps of the focusing device of the electron beam are extended by metallic deflecting electrodes placed in parallel relation to said stair-steps and electrically insulated from these latter by means of insulating layers. Said electrodes are brought to different potentials, the polarities and values of which depend on the direction and amplitude of deflection to be obtained.
