摘要
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.
