In a metal vapor laser apparatus of this invention, a cathode electrode side end portion (7) is made longer along a tube axis than an anode electrode side end portion (9). A distance (d1) between a cathode side end of the discharge tube (2) and a cathode electrode (10) is longer along a tube axis direction than a distance (d2) between an anode side end of the discharge tube (2) and an anode electrode (12). |
