Abstract

In pulse-periodic, sealed-off e-beam-sustained, and TEA CO₂ lasers, a space discharge contracts after 10³—10⁶ shots. This phenomenon is now attributed to the formation of electronegative complexes like ${CO}_{3}^{-}$ and ${CO}_{4}^{-}$ whose concentrations became comparable with the electron concentration as the O2 content in the gas mixture reaches 0.5-2%.
