张霞萍 %A 刘友文 %J 物理学报 %D 2011 %I %X Based on the modified Snyder-Mitchell model, the optical fields that are produced by two collinear Laguerre-Gaussian solitons (LGS) in a strongly nonlocal nonlinear medium are studied. Various novel kinds of solitons on the profiles which depend on the model-index and the relative amplitude of LGS are shown. It is the phase vortices of the LGS that lead to the optical singularities. The many-ring soliton is produced first with the collinear component LGS. The optical field may rotate in propagation, and the angular velocity of the spiral soliton is given. %K strongly nonlocal nonlinear media %K Laguerre-Gaussian solitons %K collinear propagation %K phase vortices
