Abstract

In this paper, the effect of discharge region temperature on the yield of singlet oxygen (O2 (a 1∆g)) in an electric discharge oxygen iodine laser is theoretically studied to analyze optimum discharge conditions. This study, was done by considering the saturation of O2 (a 1∆g) due to super-elastic electron collisions and O2 (a 1∆g) dissociation by electron impact. Rate equations were solved using two terms approximation of Boltzmann equation. The results show that when the electron temperature was in the Te= 1.9-2.1 eV range, it causes removing the main part of the atomic oxygen O (3P) from the discharge region, and the maximum yield of O2 (a 1∆g) was obtained to be about 45%.
