Paper Abstract

A vortical structure of second harmonic (SH) field excited in quadratic nonlinear medium by combined beam composed of two hollow Bessel beams of fundamental frequency is analyzed. An emergence of the pairs of single-charged vortices in SH beam caused by interaction of Bessel vortices is revealed. Experimentally, splitting of frequency-double Bessel vortex of topological charge into 2m single-charged vortices was observed.
