The patent discloses an improved ion-laser system which uses a cold, perforated-wall hollow-cathode electron-beam discharge to produce a high energy, high intensity self-collimated electron-beam. This provides a high efficiency, high power continuous wave or pulsed ion-laser oscillations in both visible and ultra-violet ranges.
