We have found an approach to constructing a novel class of Laguerre-Gaussian (LG) beam using a superposition of the known single accessible soliton solutions. Choosing appropriate values of soliton parameter, one can make up novel LG beams, such as asymmetric necklace beams and gear beams. The shape of superposition beams can be controlled by picking different topological charges.

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.
