摘要
Spatial optical solitons in nonlinear optics occupy a very important position, while most of the theories are obtained under paraxial constraints, and can not meet the application under the condition of the large incident angle of the initial beam. One-dimensional nonparaxial spatial optical solitons in nonlocal nonlinear media using Helmholtz theory are investigated. An exact analytical solution to the nonlocal nonlinear nonparaxial propagation equation in the cases of high and weak nonlocalities is deduced. It's numerically found that the degree of nonlocality can affect the widths of nonlocal soliton beams, but has no effect on their stabilities. Contrarily, nonparaxiality can affect their stabilities, but has no effect on their widths.
