Abstract

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.
