Evolution of on-axis intensity of anomalous hollow Gaussian beams in highly nonlocal nonlinear media

In this paper, we focus on the on-axis intensity evolutions of anomalous hollow Gaussian beams in highly nonlocal nonlinear media. It is found that the evolution of on-axis intensity is always periodic and the incident power of the beams plays a key role. By selecting the different amplitude of the...
