It would be possible to develop purely chemical high power pulsed laser systems based on so called photon branchin chain reactions. In such type of reactions induced emission OF photons in the course of the chain reaction exceeds their expense to initiate the reaction. In our works a well-ar ued and fundamentally new way to bring about photon branc!in chain reactions, based on nonresonant interaction between I$ laser radiation and dispersed chemically actlve medja, has been advanced. It consists in introducing finely dispersed particles (e.g. passivated metal articles) into the active medium of HF or DF CO2 laser. TRe heating under the action of IR laser radiation causes the evaporation of particles and initiation of the chain reaction (Me t FZ = MeF t F). In this work we investi ated theoretically a ,pure chemical pulsed H2 F2 ampliyier with medium containing dis ersed particles of aluminium. We based on the authors’ own mul!ilevel model of HF laser allowed for the rotational nonequilibrium and anharmonicity of the HF molecules. Numerical calculations of chemical kinetics equations, vibrational relaxation e uations, heat balance e uation, equations for the temperature and radius of the aquminium particles subject t o evaporation in the HF laser field and the radiation transfer equations have been performed. We have found new dynamic regime of photon branching in dispersed medium of HF laser -wave re ime of the pro a ation of branchin chain reaction.

基于所谓的光子支链反应，开发纯化学高功率脉冲激光系统是可能的。在这种类型的反应中，在链式反应过程中引起的光子发射超过了它们引发反应的费用。在我们的工作中，我们采用了一种非常常用的、全新的方式来产生光子分支!基于I$激光辐射与分散的化学活性介质之间的非共振相互作用，提出了链式反应。它包括在HF或DF CO2激光器的活性介质中引入精细分散的颗粒(例如钝化的金属颗粒)。在红外激光辐射的作用下，加热导致颗粒蒸发并引发链式反应(Me t FZ = MeF t F)。在这项工作中，我们从理论上研究了一种纯化学脉冲H2 F2放大器，介质中含有分散的铝颗粒。我们基于作者自己的判断!高频激光的能级模型考虑了高频分子的转动非平衡性和非调和性。对化学动力学方程、振动弛豫方程、热平衡方程、高频激光场中受蒸发的铝粒子的温度和半径方程以及辐射传递方程进行了数值计算。我们发现了HF激光在分散介质中光子分支的新动态机制——支链反应发生的波时间。在这种情况下，efr%c?我离开了我!h ?%输入?分散粒子对高频的吸收小于高频放大器的l1l。结果表明，当混合压力为1 bar时，使用浓度为&log cni '、直径为0.1微米(h = 0.4 ml)的铝颗粒，在HZ F2中输出的能量(L = 4 m)超过输入辐射能量的30倍。本出版物中所描述的研究部分是由第5号基金资助的。国际科学基金会MXOOO资助。粉末发光团中类激光效应的QThG20研究

Time s is measured in units of the laser relaxation oscillations period. We have shown that Eq.

Our analysis assumed that the delay 8 is an O(1) quantity but in many experiments 8 is numerically larger. We have modiZied the analysis in (1.1 and have found that large delays may lead to a secondary bifurcation to quasiperiodic intensity oscillations.
