In the work, the empirical Hurst’s law, the wavelet-analysis and mathematical methods of nonlinear dynamics are used for the first time for the EBCD laser output pulses analysis. It has been shown that among a great number of the processes occurring in active medium, there is certain process manifests itself in peculiar features of the laser radiation time characteristics and introduces an element of unpredictability. The criterion is offered for the correctness of EBCD laser mathematical models being developed. The research of the frequency structure of EBCD laser output pulses was carried out on the base wavelet-analysis. It is shown that the transition to chaos in the EBCD laser dynamic system occurs through the period duplication.
Key words: nonlinear effects / Hurst’s law / an element of unpredictability / the period duplication
