摘要: 对Cl/HN3/I2产生NCl(a)/I激光的过程进行了化学动力学计算,主要考察了Cl,HN3和I2的初始粒子数密度及其配比对小信号增益系数的影响。结果发现,当温度为400K, 初始Cl粒子数密度为1×1015,1×1016和1×1017cm-3时,小信号增益系数分别达到1.6×10-4,1.1×10-3和1.1×10-2cm-1,获得最佳小信号增益系数的HN3和I2的初始粒子数密度分别为初始Cl粒子数密度的1~2倍和2%~4%。同时,对Cl,HN3和I2配比对小信号增益系数和增益持续时间的影响进行了讨论。

Abstract: The chemical kinetics of Cl/HN3/I2 laser has been simulated and the effect of the density of Cl, HN3 and I2 on small-signal gain has been obtained and discussed. The results show that the coefficient of smallsignal gain could be 1.6×10-4,11×10-3 and 1.1×10-2cm-1 at 400K when the initial density of Cl was 1×1015, 1×1016 and 1×1017cm-3 respectively, the initial density of HN3 and I2 for an optimal coefficient of smallsignal gain should be 1~2 times and 2%~4% of the initial density of Cl respectively.-
