  • 利用1+2维Snyder-Mitchell模型讨论了柱坐标系下光束传输过程,得到了强非局域非线性介质中光束稳定传输的拉盖尔高斯型解,即空间光孤子解,并得到了入射光束稳定传输的临界功率.图示展现了几个低阶光孤子解,并发现了强非局域非线性介质中存在圆环形光孤子.

     

    This paper discusses the optical beam (1+2D) of suitable input power propagating in the strong nolocal nonlinear media,which is governed by the Snyder-Mitchell model in the cylindrical coordinate.An exact analytical solution in 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.
