摘要
本文从理论上研究了主克尔型介质中非束缚态空间亮孤子的传输行为数值计算结果表明：在主克尔型χ（３）＋χ（５）介质中可以传输非束缚态空间亮孤子传输稳定性与其背景平面波的横向渐近传播常数ｑ和χ（３），χ（５）系数有关，非平凡相位因子在三、五阶效应竞争中的平衡作用。
Propagation of the unbounded bright spatial soliton in non Kerr type media is studied. Numerical calculation show that propagation of the unbounded bright spatial soliton can take place in the so called cubic quintic nonlinear medium.The stability of propagation depends on the values of the asymptotic wave number of the background plane wave q,and of χ (3) ,χ (5) ,where the nontrivial phase variation also plays an important role.
