摘要  利用有限差分方法中的类Crank_Nicholson格式对光折变空间孤子方程进行数值求解,给出了光折变空间明孤子在铌酸锂晶体中的演化过程,证明该方法具有稳定性好、运行效率较高的特点. The solution of the scalar wave equation of the photorefractive spatial solitons is considered through the finite-difference method (FDM). The evolution of the photorefractive bright spatial solitons is investigated numerically in lithium niobate crystal. It is shown that the FDM yields a large improvement in stability and computational speed.
