Patent ID: 8331416

Claim:
A stripline laser, comprising: two plate-type electrodes having flat sides disposed opposite one another and defining a discharge space therebetween; a gas mixture containing carbon dioxide as a laser-active medium disposed between said plate-type electrodes; resonator mirrors, one of said resonator mirrors disposed at each of end sides situated opposite one another of said two plate-type electrodes, said resonator mirrors forming an unstable resonator parallel to said flat sides; a passivation layer disposed on each of said flat sides situated opposite one another, said passivation layer, in a case of at least one of said two-plate-type electrodes, containing silicon dioxide in a region covering at least one partial area of said flat side; and said two plate-type electrodes disposed a distance apart such that an attenuation of laser beams in a 10.3 μm and in a 10.6 μm band is greater than an attenuation of laser beams in a 9.3 μm band and/or in a 9.6 μm band.
