Abstract

Physical processes proceeding over the active electrode surfaces and their influence on a spatial plasma homogeneity of the volume discharge as well as the energy parameters and the resource of sealed-off pulse-periodical TEA-CO₂ lasers have been investigated. Microstructures of the active electrode surfaces which lead to the increase of autoelectronic emission have been found to be formed under the influence of the volume discharge plasma and the products of plasma chemical reactions. The increased values of these currents initiate the formation of local channels in the cathode area of a volume discharge and initiation complete transition of volume discharge into a local one. The electrode materials, which provide the formation of stable volume discharges are determined and a maximum resource of sealed-off TEA-CO₂ lasers is achieved.
