强非局域非线性介质中的完美厄米高斯高阶孤子(英文)

Elegant Hermite-Gaussian higher order solitons in strongly nonlocal nonlinear media

本文得到了强非局域非线性介质中的一类高阶空间孤子,即完美厄米高斯高阶孤子.此类高阶孤子在入射面处的场分布与完美厄米高斯光束束腰处的场分布相同.在传输过程中,其场分布呈周期性演化,周期为△z=π/β_0.

A family of higher-order solitons called elegant Hermite Gaussian higher-order soliton (EHGHOS) in the strongly nonlocal nonlinear media is introduced. The transverse distribution of EHGHOS at the entrance plane is the same as the waist of elegant Hermite Gaussian beam. And it presents as periodical evolution with the period △z = π/β_0 when propagates.
