Electrical and gain characteristics of a multiatmosphere UV-preionized CO2 laser
Abstract
The scaling parameters of a UV-preionized TE CO2 laser which permit the direct comparison of small-signal gains as a function of laser pressure have been investigated in the pressure range of 4-19 atm. Careful measurements of the gain as a function of laser pressure in both the 9.4 and 10.4 microns vibrational bands were made under the appropriate scaling conditions. A theoretical model for the gain incorporating regular, hot band and sequence band rotational lines, with proper account taken of non-Lorentzian line overlap effects, predicts the observed pressure dependence of the small-signal gain.
