摘要
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.对矩坐标系和旋转坐标系下的高阶空间光孤子进行了比较,分析了厄米高斯型解和拉盖尔高斯型角两类孤子之间的联系,并提出了两类孤子之间的转化可能.
The optical beam on the suitable input power propagates in the strong nolocal nonlinear media governed by the linear model. An exact analytical solution of the Hermite-Gaussian form was obtained by a new tentative solution. Compared with the exact analytical Solution of the Laguerre-Gaussian form, it is found firstly that the matrix solitons to the rectangular coordinates and the necklace solitons to the cylindrical coordinates are interacted with each other, and some matrix solitons can transform to the correlative necklace solitons in the strong nonlocal media.
