Abstract
A transverse excitation atmospheric pressure laser employing a preionizing flash board formed on one of the sides of the laser tube. The side wall of the laser tube acts as an insulating support plate having a backing plate on the outside surface and a set of subsidiary electrodes on the inside surface. The subsidiary electrodes are short cylinders bonded to the inside surface of the support plate and having a flanged portion at the opposite end. The preionizing discharge takes place between adjacent subsidiary electrodes in the region between the flanged portions and is thus removed from the support plate. The material for the flanged portions has a high melting point and a low sputtering capability. A U-shaped enclosure provides a grounded housing for all the high voltage components and also provides a path for the discharge currents.
