摘　　要：用数值方法模拟异色光伏孤子的相互作用 .结果表明孤子间相互作用是非弹性的 ,相互作用的孤子只在有限的传播距离内保持孤子形状 .不同频率光伏孤子间的相互作用除了相互吸引外 。The interaction between photovoltaic spatial solitons with difference wavelengths in photovoltaic-photorefractive crystals is investigated by numerical method. Our numerical study indicates that the interaction between these solitons is inelastic, and these solitons keep their shapes only within some propagation distance. Besides the attraction with each other, the energy of soliton would be coupled from one waveguide to other waveguide during propagation.
