Abstract

The most common method of "pumping" the active medium, in the field of high-power CO2 lasers, is still the self-sustained electric discharge[1-4]. This paper presents the experimental results for an electrode configuration citied in an ealier work [5,6]. The experimental investigations were carried out in the experimental chamber of a high-power fast-flow carbon dioxide laser facility [7] in which the circulation of the gas occurs in a closed loop as described in [8]. The measured V-I characteristics are used to analyse the characteristic properties of the excitation system. These investigations help to illuminate the general quality of the glow discharge and define the region of application of the electrode configuration for exciting the gaseous medium of a CO2 laser. The electric discharge characteristics are tested with a gas mixture of CO2 : N2 : He in the proportions 1 : 2 : 7 at an operating pressure in the range 20 - 80 hPa and a gas flow velocity which is variable from 30 to 100 m/s and the length of the discharge zone is between 10 and 70 mm along the gas flow.
