Abstract

Results of experiments on controlling the position and length of the filamentation zone of femtosecond laser pulses in atmospheric path length 150 m using different initial spatial focusing and defocusing. The obtained distribution of filaments along the filamentation domain, measured dependence the length of the filamentation zone of the numerical aperture of the beam, its initial radius and pulse power. Registered emission spectra of the illumination targets of various materials, placed in the filamentation zone remote from the radiation source.
