Paper Abstract

Wave caustics formed after short pieces of a multimode fiber have a vortical nature. Such assertion expressed by M. Berry as early as 1980, is the subject of consideration of the given experimental work. The caustic near its cuspidal point contains the vortices in the coupled states with the twofold topological charge. Transition of the wave caustic is accompanied by the vortex sign conversion. At the cuspidal spike the two vortices are unified in the vortical unfolding.
