摘要
采用数值模拟方法研究了双光子屏蔽孤子的动态演化和自偏转.结果表明,在忽略扩散和损耗的情况下,屏蔽孤子能在双光子光折变晶体中稳定传播.晶体的扩散效应使光束的中心发生偏转.
The evolution and self-deflection of two-photon screening spatial solitons in photorefractive crystals were numerically investigated.The results show that the two-photon screening spatial solitons can propagation in the crystal in the case of neglecting the diffusion and loss.The diffusion effect can cause the center of the beam move on a parabolic trajectory.
