强非局域非线性介质中拉盖尔-高斯型光孤子相互作用
Interactions of Laguerre-Gaussian solitons in strongly nonlocal nonlinear media
摘要
Abstract
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.关键词
