VISIBLE SIDE-LIGHT EMISSION PROPERTIES OF A CO2–N2–He PLASMA INDUCED BY THE CO2 LASER RADIATION FIELD

Abstract

The effect of laser action, in CO₂ laser plasmas, on the spontaneous emission in the visible spectral region is studied by means of a phase‐lock technique. The results reveal that direct collisions between molecules in the primary laser cycle and highly excited states have an important influence on the properties of the plasma.
