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 17000 °K (±5%) 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.This publication has 4 references indexed in Scilit:
