Survey of Electric Discharge CO2 Lasers

  • A. J. DeMaria

Abstract

Based on research performed with sealed-off discharge tubes and with slow flowing gas lasers, most researchers believed, up until several years ago, that an upper limit of approximately 100 watts per meter of discharge length was obtainable from CO2 lasers. In 1967, a power output of 800 watts in a 30 cm long CO2: N2:He discharge was obtained at United Aircraft Research Laboratories by convectively cooling the CO2 laser medium by rapidly flowing the gas through the discharge region. In the fall of 1968 and in the spring of 1969, the power was pushed up to 9 kW and 11.5 kW per meter respectively. As a result of this work, the merits of the convectively cooling process in electrical discharge CO2 lasers has now become well known1–10.
