摘要 研究了对数型非线性电介质中低振幅空间明孤子的动态演化特性.结果表明,在低振幅条件下空间明孤子的解析表达式与数值计算所得到的结果十分吻合.入射波为明孤子波时,能够在对数型非线性电介质中稳定传播.强度包络宽度变化与光源峰值功率成反比. Dynamical evolution of spatial bright solitions in cogarithmically nonlinear electric media under weak amplitude condition was studied. The analytic expression for the spatial bright solitions obtained under the weak light intensity agrees well with the results obtained by the numerical calculation.When an incident optical beam is bright solition, this beam propayates along a linear path with its shape kept unchanged. It is revealed that the variation of the beam width is inversely proportional to the peak of the source.
