Abstract
An electrically excited gas laser includes coaxial hollow-cylindrical electrodes defining a discharge space between the electrodes. A resonator mirror is disposed at each respective end of the discharge space. At least one of the resonator mirrors forms an intersection line with a cylindrical surface being coaxial with the electrodes and the intersection line extends obliquely relative to the circumferential direction. The resonator mirrors form intersection lines with an axial plane of the electrodes and the intersection lines extend substantially at right angles to the axis. At least one of the resonator mirrors extends over only a portion of the circumference of the discharge space.
