Abstract

Electric and thermal properties of the working medium are presented for a flow carbon-dioxide laser generating a beam with a power of the order of some kilowatts. The medium was excited by a transverse stationary dc glow discharge. Floating potential and translational temperature distributions and the magnitude of cathode and anode potential drop were measured. Floating potential was determined depending on spatial coordinates, electric discharge current and on the flow rate. The degree of warming up the medium was analyzed, thermal flux directions and intensity were determined and optical heterogeneity of the gas mixture was evaluated. The measurements were carried out by the use of a combined probe.
