PURPOSE:To facilitate fixation of a return path to a metal vapor laser tube, simplify holding and arrangement structure, and improve resistance to shock and vibration by supplying carrier gas to the one electrode side of the laser tube through a tube, which has a shape causing a greater ion loss than a laser capillary, in a carrier gas reservoir and to the other electrode side directly from the carrier gas reservoir. CONSTITUTION:A tube 3 having a shape causing a sufficiently greater ion loss than a laser capillary 11 is arranged in a carrier gas reservoir 23. A first connection member 4 to supply carrier gas to the anode 12 of a metal vapor laser tube 1 through the tube 3 and a second connection member 5 to supply carrier gas from the carrier gas reservoir 23 to the cathode 13 are installed. The first connection member 4 has a flexible tube 42 in the middle to prevent excessive stress from being applied to the metal vapor laser tube 1. The second connection member 5 also has a flexible tube 52 in the middle to prevent excessive stress from being applied to the metal vapor laser tube 1. |
