We describe the modelling of a pulsed iodine laser that operates by first producing iodine atoms from photodissociation of El, followed by energy transfer with electronically excited oxygen Oy (1). 35 rate processes are considered. By using Bunge-Kutta-Gill integral method in computing, the performances of such oxygen-iodine pulsed lasers are obtamed under a series of operating conditions. The results show that this type of pulsed oxygen-iodine chemical lasers prossesses high chemical efficiency. Increasing... We describe the modelling of a pulsed iodine laser that operates by first producing iodine atoms from photodissociation of El, followed by energy transfer with electronically excited oxygen Oy (1). 35 rate processes are considered. By using Bunge-Kutta-Gill integral method in computing, the performances of such oxygen-iodine pulsed lasers are obtamed under a series of operating conditions. The results show that this type of pulsed oxygen-iodine chemical lasers prossesses high chemical efficiency. Increasing the partial pressure of O2(1) is shown to be the major path to improve the performances. 采用闪光灯光解RI得到碘原子,再与电子激发态氧O_2(~⊿)传能产生脉冲碘激光的模型。此模型包括35个化学动力学过程。采用Runge-Kutta-Gill积分法求解,得到的结果表明脉冲氧碘化学激光器具有高的效率,提高激光器性能的关键在提高O_2(~1⊿)的分压。 A two-dimensional theoretical model for predicting the diffusional CW oxygen-iodine laser performances is presetted. The parallel mixing at constant lateral pressure between a pair of primary and secondary streams is assumed. A set of parabolic partial differential equations are solved using the finite-difference techniques. The change of specific power with flow direction and the effect of the concentration of O2(1) on specific power are studied. 采用二维理论模型研究连续波扩散型氧-碘化学激光器的性能。假设主、副气流间在侧向压力不变的情况下进行混合和反应,采用有限差分技术来求解偏微分方程组,考察了比功率沿气流方向的变化以及O_2(~1⊿)浓度对比功率的影响。 This paper demonstrates for the first time the feasibility of an electrically initiated pulsed oxygen-iodine laser which can be initiated efficiently by low energy electrons. An O2(1)-CH3I-N2 mixture has been made to lase by electrical initiation with an output energy of 130mJ. The electrical efficiency is 350 times higher than that obtained with photo-initiation. 报道首次利用放电引发方法实现脉冲氧碘化学激光器的研究结果.证实低能电子也能很有效地引发氧碘激光反应.在O_2(~1(?))-CH_3I-N_2体系下激光能量输出达130mJ,电效率比光解方法高350倍.
