Paper Abstract

We report on the observation of far field spatial distortions of a Bessel beam after passing through a Kerr liquid. A coaxial ring structure has been observed to occur at some threshold power. It consists of two closely spaced (1.5 - 3.5 mrad) sharp rings of comparable intensity and a diffuse inner ring of smaller intensity separated by 8 - 9 mrad. Evolution of the far field pattern with moving the sample along the propagation path of the Bessel beam shows strong dependence of beam distortions upon the position of the sample. The phenomenon is supposed to be due to nonlinearly induced phase aberrations resulting in the distortion of angular spectrum.
