Abstract

PURPOSE:To arrange so that dust may not deposit on a mirror by applying a partial voltage of a laser power supply even between a cathode and one mirror support of two mirror support to allow an auxiliary discharge. CONSTITUTION:In a laser tube 3, a mirror support 4 consisting of an anode and a mirror support 4' made up of a cathode 7 and an auxiliary electrode are provided. Then an electric discharge is caused between the mirror support 4 and the cathode 7, and a laser output 8 is obtained by a combination light resonator composed of mirror 5, 5'. In addition, an electric discharge is caused even between the mirror support 4' and the cathode 7, so that deposition of dust on a mirror 5' installed on the mirror support 4' from the interior of the laser tube 3 is prevented. Also a main electric discharge between the mirror support 4 and the cathode is prompted by generating a preliminary discharge between the mirror support 4 which becomes an auxiliary electrode and the cathode.
