摘要: An electron-beam-pumped laser includes a cathode-ray tube containing a laser crystal, an electron gun for producing an electron beam including a multi-element focusing electrode layer on an inner surface of the tube for effecting focusing of the beam on the laser crystal, and a multi-element deflection electrode layer on an inner surface of the tube for effecting scanning of the beam across the laser crystal. The laser crystal is disposed on a metal heat-conductive support which is adapted for accurately positioning the laser crystal in closely spaced relationship with respect to the electron gun and to a laser light emitting window of the tube.

摘要: An electron-optical device comprising a cathode ray tube with an envelope comprising an electron gun for producing an electron beam, whose inner surface carries a multi-element layer electrode such as a helical structure formed from a high-ohmic resistance material, which structure constitutes a focusing lens. A deflection system is used for moving the focused electron beam across a laser crystal arranged in the tube. Due to the laser action of the crystal, a scanning laser is realized. The laser light leaves a window in the tube envelope. The window extends at an angle between 20° and 60° to the longitudinal axis of the tube which is parallel to the electron beam incident on the laser crystal. Used in, inter alia, projection tubes and electron beam-pumped lasers (for example, scanning lasers).
