Abstract
Disclosed is a laser apparatus for effecting laser oscillation by exciting a laser medium by discharge between an anode and a cathode opposedly arranged to each other in a discharge tube, comprising means disposed in the discharge tube to support both the electrodes movably along the axial direction of the discharge tube so as to prevent warp of the electrodes on laser oscillation and keep the parallelism therebetween with high accuracy. Also disclosed is a laser apparatus comprising main discharge means for effecting laser oscillation by exciting a laser medium by generating discharge, and preionization means for generating ionization previously to the discharge by the main discharge means so as to stabilize laser oscillation under a high gas pressure and a high current density.
