Abstract:
1. A slab laser, comprising: two plate-type metallic electrodes having flat sides disposed opposite one another and defining a discharge space, and end sides disposed opposite one another; a gas mixture containing carbon dioxide CO resonator mirrors, one of said resonator mirrors disposed at each of said end sides of said two plate-type metallic electrodes, said resonator mirrors forming an unstable resonator parallel to said flat sides; and a dielectric layer, wherein at least one of said flat sides facing one another is provided with said dielectric layer on an entire area of said one flat side, a thickness of said dielectric layer being greater on at least one partial area than in a remaining region of said one flat side, said thickness extending toward said flat side of the other one of said plate-type metallic electrodes and said thickness being less than a distance separating said flat sides of said plate-type metallic electrodes from one another and said dielectric layer assisting in selectively suppressing of undesired modes.
