Abstract :
The multiline behavior of a ballast resistance helical TEA CO2 laser incorporating hot CO2 as an intracavity absorber has been studied. Simultaneous laser oscillation on 
, and 
lines of 10.6 μm has been obtained reliably. A rate equation model has been developed for the hot CO2 absorber and is incorporated with the model for the multiline TEA CO2 laser for calculating laser intensities on 
, and 
lines of the 10.6 μm band in the presence of the absorber. The theoretical calculations agree quite well with the experimental observations. These studies show that a hot CO2 column of Proper length and temperature inside a TEA CO2 laser cavity can produce simultaneous laser oscillation on at least three rotational lines , and of the 10.6 μm band with almost equal intensity.
