Modeling of a Pulsed CO/N2 Molecular Laser System - Part II. Effect of Mixture Components and Temperature Variation

摘要

The CO molecular laser model described in a previous publication has been used to investigate the effect of molecular mixture components and kinetic temperature variations on improving the gain of low lying CO infrared transitions. Gas mixtures involving diatomic molecules with both larger and smaller vibrational level spacing than CO were investigated. Vibrational pumping of CO by a molecule having smaller vibrational spacing lead to negligible laser gain predictions due to the nonspecific nature of vibrational exchange processes. The largest predicted gain in the low lying transitions of CO was found for N2/CO mixtures at 77K in which appreciable gain in the 2-1 transition was found. (Author)
