High Temperature Alumina Discharge Tube for Pulsed Metal Vapor Lasers

Abstract

An alumina high temperature gas discharge tube with cold windows has been constructed for the investigation of metallic vapor lasers. It offers vacuum tight containment to 1400°C, and flexibility with respect to active material, discharge diameter, type of excitation, and output windows. Pulsed laser oscillations in lead, manganese, and copper have been observed in this apparatus.
