Abstract

The interaction of two in-phase and out-phase anomalous hollow Gaussian beams in strongly nonlocal nonlinear media (SNNM) is investigated. The analytical expression describing the two beams co-propagating in SNNM is derived. It is found that when two anomalous hollow Gaussian beams separated by a distance at the source plane propagate together in SNNM, the evolution of two beams varies periodically. The two beams always attract each other, whatever the relative phase of the two beams is in-phase or out-phase. At the interactional region, many interference fringes appear, and the central intensity is a prominent peak for two in-phase beams; however, it is equal to zero for two out-phase beams.
