Abstract

The effect of NCl(a¹Δ) self-annihilation on the production of NCl(a¹Δ) and energy extraction of NCl(a¹Δ)-I laser was simulated by means of a simplified continuous flow F-P resonator model. The results show that NCl(a¹Δ) self-quenching is an important influence on NCl(a¹Δ) production and energy extraction of NCl(a¹Δ)-I laser and is the most important channel for transport losses of NCl(a¹Δ). The efficiency of NCl(a¹Δ) production with NCl(a¹Δ) self-annihilation is much less than that without NCl(a¹Δ) self-annihilation. The optimal location for cavity resonator, the profile of power density along the flow direction and the total power are dramatically dependent on the order of magnitude of the rate constant of NCl(a¹Δ) self-quenching reaction. The results show that it is necessary to do more works on the measurement of the rate constant of NCl(a¹Δ) self-annihilation reaction and its dependency on temperature in order to accurately analyze, design and value AGIL(All-gas Phase Iodine Laser).
