Sealed-off TEA CO2 lasers with pulse repetition rate up to 5 kHz for technological a

摘要

Abstract: The aim of this work was to investigate the influence of plasma-chemical reactions products, heat processes on the electrode surface, and the degree of coordination of pump pulse generator on the forming conditions of volume discharge in the working mixtures of sealed-off TEA CO$-2$/ laser. The main factors limiting the pulse repetition rate were determined. Some versions of sealed-off TEA CO$- 2$/ lasers with the pulse repetition rate of 1 - 5 kHz and the pulse radiation energy of 10 - 50 mJ were realized. !17
