Influence of the main factors on the efficiency of coherent emission as a result of reaction of hydrogen with fluorine

A fairly simple kinetic model is proposed for th H₂+F₂ laser in which allowance is made for the principal features of the physicochemical kinetics. This model is used to calculate the dependences of the efficiency and duration of emission of coherent radiation from a laser amplifier on the degree of initiation, initial chemical composition of the mixture, duration of the initiation pulse, concentration of the photoinitiating component, rate of initiation (for constant initiation pulse duration), pressure in the mixture, and oxygen concentration. The kinetics of a laser oscillator is also considered.
