Using the coherent density approach, we study the propagation dynamics of incoherent bright and dark beams in biased photorefractive crystals. We show that, under appropriate initial conditions, bright as well as darklike incoherent quasi-solitons can be established in this material system. Our numerical simulations demonstrate that the coherence properties of these beams can be significantly affected by the self-trapping process.
利用相干密度方法，我们研究了非相干亮光束和暗光束在偏置光折变晶体中的传输动力学。我们表明，在适当的初始条件下，这种材料系统中可以形成亮的以及类暗的非相干准孤子。我们的数值模拟表明，这些光束的相干特性会受到自陷过程的显著影响。
