Abstract

The results of the experimental and theoretical DSPIL modeling are presented. The parameters of the generation pulse (energy, duration, delay time) are measured for the series of perfluoriodide laser compounds under pumping conditions imitating the space solar radiation spectrum. The time dependence of the radiation spectrum was measured for the pumping pulse. The spectrum of this pulse corresponds to the ABB spectrum with temperature 6000 K in the pulse beginning and 3500 K in the end. The generation energy ratio (E₁₀/E₁) in repeatedly pumping pulse action without the active laser medium change was measured in this experiment. The empirical linear dependence between quantities 1n(E₁₀/E₁) and 1n(k₃/k₄) is received, where E₁ and E₁₀ are the energies of generation pulse after first and tenth pumping pulses. The mathematical model of DSPIL, containing the main kinetical processes description, is developed. The computing evaluation of the energy characteristics of DSPIL are presented.
