High-pressure volume discharges in gas lasersa Lebedev Physical Institute, Russian Academy of Sciences, Leninsky prosp. 53, Moscow, 119991, Russian Federation Investigations of pulsed volume discharges at pressures atm in nitrogen, CO:N:He mixtures, and mixtures of noble gases and halogens are reviewed from the point of view of their use in lasers. The review examines self-sustaining discharges in which the initiating electrons are produced by illuminating the gap with an auxiliary spark, with an x-ray source, etc., and non-self-sustaining discharges with external gas ionization by fast electrons. Data on the contraction of volume discharges are presented. A special section is devoted to high-pressure discharges in CO lasers.
