Experimental Study of a Laser Sustained Air Plasma

Abstract

An experiment was performed to determine the temperature distribution within a stationary plasma in atmospheric air, produced by a continuously operating CO2 laser. A peak temperature of 17,000K was found to exist at a point 1.1 cm ahead of the focal point. The radiation surrounding the hot plasma core was found to consist, primarily, of the first negative system of nitrogen.
