| 摘 要： | 文章基于强非局域非线性空间中
的线性模型利用试探调制解的方法得到了1+2维矩空间的厄米高斯型解。
厄米高斯型解和拉盖尔高斯型解都为高阶模传输光孤子解，但其所选择的坐标基不一样，使得高阶模孤子的特性也不同。
文章首次分析了两类孤子之间的联系，并提出了两类孤子之间
的转化可能。

| Abstract: | In this paper, it is discussed that the optical beam (1+2D) on the
suitable input power propagates in the strong nolocal nonlinear
media,which is governed by the Snyder-Mitchell model in the
cylindrical coordinate .
An
exact analytical solution with Laguerre-Gaussian form is obtained
.It is shown that the solution in the Gaussian form is the
lowest-order mode. It is found for the
first time that the necklace-ring spatial soliton exists in the strong nonlocal media . |
