Numerical simulation of an all gas-phase iodine laser based on NCl3 reaction system

A numerical simulation code for an all gas-phase iodine laser based on the NCl3 reaction system is developed. The model is a one-dimensional, multiple-leaky-stream-tubes kinetics code combined with all the known rate equations to date. To confirm the validity of this simulation code, the calculated results are compared with the experimental results obtained in other laboratories. The results of computer calculations utilizing this model are in good agreement with those experimental results. This agreement shows that the code is capable of precisely predicting the small signal gain and laser output for a given set of flow conditions. Using this simulation code, we defined the flow rates and the nozzle configuration that should allow laser oscillation based on NCl3 reaction system to be achieved. The calculations suggest that a laser output power of 410 mW can be obtained under optimum conditions with facilities available in our laboratory
