ABSTRACT:
A gas laser device comprises a discharge space in which a laser gas is excited by electric discharge, the discharge space being in the form of a slab whose section perpendicular to a laser optical axis has a longer side and a shorter side; and laser resonator mirrors disposed at both ends of the discharge space, respectively. The laser resonant mirrors constitute a negative branch unstable resonator in a first dimension of longer side of the discharge space section, and a laser beam is obtained at one end of the longer side of the discharge space section.
