Abstract

PURPOSE:To provide a copper vapour laser device which is capable of generating a laser ray larger in output and recovering remarkably the output decreased due to a drop in temperature of a discharge tube by a method wherein a discharging region is made to be divided into plural parts so as to decrease its inductance. CONSTITUTION:All of Ne<+> ions in two discharging regions are trapped together with copper vapour ions by a common electrode 6b, so that N<+> ions and copper vapour ions are almost restrained from deviating from discharge tubes 1b and 1c. Concerning the discharge tubes 1b and 1c, negative gigh voltage exciting pulses are applied between an anode 5b and a cathode 6b, and an anode 5c and the cathode 6b respectively, where the anodes 5b and 5c are made to be zero in potential, therefore a negative high voltage is impressed on the common cathode 6b. As mentioned above, provided that the discharge tube the same in length and diameter is divided into two discharging regions which are made to discharge, the inductance can be remarkably decreased. A reduction in inductance is one of important factors which improve a discharge tube in excitation efficiency.
