Abstract
Detailed numerical calculations of electron transport coefficients and vibrational excitation rates in a He:N2:CO2 gas laser discharge have been carried out over a range 1×10−16≤E/N≤5×10−16 V cm2 for several gas mixtures. Comparison of the results indicate that the vibrational excitation processes in the CO2 molecule scale with the average electron energy and are approximately invariant with respect to gas mixture. At a fixed value of electron energy, the dominant effect of gas mixture variation is to modify the vibrational excitation rate into the nitrogen. The effect of gas mixture variation on electron drift velocity is greatest in CO2–He mixtures, but is substantially reduced when a small fraction of N2 is added.This publication has 8 references indexed in Scilit:
