摘要: In this paper, we present a study on the propagation of the symmetrical optical vortices formed by two collinear Laguerre—Gauss solitons in strongly nonlocal nonlinear media. The optical vortices, which move along the beam axis as the light propagates, result in a rotation of the beam's transverse profile. This physical reason of the rotation is the Gouy phase acquired by the component beams.
