In this paper, we investigate the nonlinear dynamics of the off-waist incident cosh-squared-Gaussian beams (CSGBs) in highly nonlocal media. The analytical expression describing nonlinear dynamics of CSGBs is derived. It is found that the evolutions of the statistical beam width and the intensity pattern of CSGBs are always periodic, which is similar to the temporal higher-order breathers in nonlinear fiber. Numerical simulations are carried out to ill...
