Abstract:
In this research, the effect of He/NO2 injection to the post-discharge region of an electric discharge oxygen iodine-laser was studied by using three-dimensional (3D) computations. Atomic oxygen atoms (O) in post-discharge O2/He flow effectively deplete singlet oxygen molecule (O2 (1Δ)). Thus precise technique of removing O atoms is very important for electric discharge chemical oxygen iodine lasers. Most important technique is through the admixing of He/NO2 to post-discharge flow which allows control O atoms. Probable chemical reactions resulted from the presence of He/NO2 in post-discharge region were studied [1]. Effect of He/NO2 combination on keeping the singlet oxygen molecule and depleting atomic oxygen along post-discharge region just before activation region of laser is evaluated. Optimum concentration and flow rate has investigated at special conditions. By changing the injection rate of He/NO2 optimum value, about 0.7 m/s, has been obtained.
