Abstract
We report the diversiform propagation of hollow Gaussian beam clusters in non-linear media with self-induced parabolic potentials. It is found that the beam cluster can present various periodically varying propagation forms by tuning the initial incident conditions. We roughly classify the initial incident cases into five types—parallel incidence, spiraling incidence, convergent incidence, divergent incidence, and mixed incidence—ground on the introduced transverse velocity parameter. The propagation characteristics, such as the evolutions of the intensity patterns, the projection trajectories, the rotating angle, the angular velocity, the center distance, the size and the phase distribution of the beam cluster, are illustrated graphically in detail. These novel forms of beam clusters presented in this paper possess complicated and unique spatial distribution and controllable propagation parameters for their potential applications in all-optical networks, optical switch, optical tweezers, multi-particle trapping, and other related fields.
