Abstract

The propagation of high-power femtosecond laser radiation through an aerosol is studied experimentally and theoretically. In the course of experimental studies, the effect of aerosol on the characteristics of the radiation filamentation region was shown. On the basis of experimental data, the time dependence of the degree of inhomogeneity of the high-power femtosecond laser radiation field due to the spreading of the aerosol cloud is found. A theoretical model is proposed that makes it possible to reproduce experimental patterns not only qualitatively, but also quantitatively.
