This paper discusses the propagation characteristics of astigmatic mixed-pattern solitons in strongly nonlocal nonlinear media. From the initial expression of the astigmatic mixed-pattern soliton, it is found that the propagation pattern of solitons can be divided into three different cases: oval type, two-petal type and four-petal type. We further derive the beam propagation expression, and solve the analytical expressions of the intensity, beam width, power and curvature of the soliton. Through numerical simulation, we made a series of graphs and carried on the necessary elaboration. The propagation dynamics are described emphatically and the propagation characteristics are discussed in detail.

Evolution Period

The evolution of elliptical hollow Gaussian beams propagating in strongly nonlocal nonlinear media is investigated. As examples, this paper mainly focuses on the evolutions of the transverse intensity and the beam width of elliptical hollow Gaussian beams with the beam order being 1 and 3. The results show that the evolutions of the transverse intensity and the beam width are both periodical and the size of the evolution period is determined by the input power. There exists the transverse reverse transform for the beam width when selecting a proper input power, which is quiet different from the circularly symmetric hollow Gaussian beams.
