The diffraction broadening of the large-aperture freely propagating Bessel beams is considered. The dependences of integral quantities characterizing the degree of transverse concentration of radiation in such beams on their axial and radial coordinates are obtained. It is shown that the Gaussian beams are better suited for channeled radiation energy transfer in a free space than the Bessel beams.
