ABSTRACT:
A laser device is capable reducing fluctuation of the beam width of the output laser beam due to abrasion of its discharge electrodes. A part of the contour shape of a section perpendicular to the longitudinal axis of the chamber of the laser device in at least one of the electrodes, which part confronts the other one of the electrodes, has a shape of a circular arc having a predetermined radius. The width of at least one of the two electrode may be substantially equal to the width of electric discharge taken place between the electrodes. Further, a conductor member may be disposed on each side of the electrode along its longitudinal axis to reduce electric field strength therearound.
