Abstract

The influence of plasma of the volume discharge on the microstructure of the active surfaces of electrodes and their autoemissive properties in CO₂ laser mixtures at atmospheric pressure is researched. A correlation between a change in a microstructure of the electrode surfaces when the autoelectronic currents are increased is stated. It results in a formation local channels in a cathode area of the volume discharge and a resource limitation of small-sized sealed-off pulse-periodical TEA-CO₂ lasers. Materials the more stable to the influence of plasma of the volume discharge providing for getting of a maximum resource (N greater than 10⁸ of pulses) are determined.
