Influence of xenon small additions in CO2–laser mixtures at atmospheric pressures on the velocity of «electrical wind» in closed volume were investigated. Xenon additions with partial pressures up to 30 Torr lead to the increase of «electrical wind» velocity on 30 – 33 %. Maximum increase of «electrical wind» velocity was established in working mixture СО2:N2:He = 1:1:3. The main aim of this work is to study the influence of xenon small additions in CO2–laser mixtures at atmospheric pressures on «electrical wind» velocity.

Key words: pulse repetition rate, average radiation power, «electrical wind» effect, unipolar crown discharge, gas addition, transverse gas blowing, gas dynamic method of gas flow velocity measurement, dynamic pressure.
