Abstract

PURPOSE:To prolong life time of laser tube and stabilize its output and optical axis by evaporating a getter film on the portions other than vacuum vessel inside the laser tube. CONSTITUTION:Mirrors 4, 5 are arranged at a right angle with laser fine tube 6 on the both sides of the said tube through vacuum vessel 8. If an appropriate voltage is applied to anode 1 and cathode lead wire 2, an electric discharge is begun through the laser fine tube and laser oscillation is started by an interaction between a laser medium generated inside the laser fine tube and the mirrors on the both sides. For prolongation of the laser tube's life, getter 7 is provided toward the center of the laser tube.
