【 摘 要 】

We investigate the propagation and evolution of multiple modified hollow Gaussian beams (MHGBs) for the off-axis incident case in highly nonlocal nonlinear media. The propagation expression of the off-axis MHGB is obtained, the evolution characteristics, such as the optical field distribution, the motion track, the off-axis distance, the rotating angle, and the rotating speed of multiple MHGBs have been discussed analytically and graphically. The results of this paper may have potential applications in related research fields such as exploring the control of multi-beam motion track and designing novel high-order beam forms.
