Abstract

A characteristic feature of pulse lasers on vapors of metals (LVM) is a large number and essential nonstationarity of physical processes determining their activity. The times of generation of radiation, population of nuclear levels, passing of light in a resonator and discharge of the accumulative capacitor through inductance of an electrical circuit appear by sizes of one order. This extremely complicates the analysis of experiments and makes practically impossible analytical research of LVM. In an impulse-periodic mode, it is necessary, in addition, to take into account the kinetics of recombining plasma, processes of diffusion and heat rejection, which determine an optimum pulse repetition rate of excitation. In such conditions the most effective in theoretical research LVM appears a method of numerical experiment
