摘要

本文利用相干密度理论研究了一维部分相干孤子在对数可饱和光折变介质中的传播动力学,特别是利用相干密度理论研究了相干光束的自俘获行为。结果表明,孤子可以平稳传播。此外,还讨论了光束的另一个动力学演化,即当相干度值偏离自俘获值集时,光束会不断地膨胀和收缩。本文还详细分析了由部分相干光束组成的相干分量的演化特性。

Notice of RetractionPropagation of partially coherent solitons in photorefractive crystal
We investigate the propagation dynamics of one dimensional partially coherent solitons in logarithmically saturable photorefractive media by using the coherent density theory, specially using this approach to study the self-trapping behavior of coherent beam. It is shown that the solitons can propagate stationary. Moreover, the other dynamics evolution of beam is discussed, that when the value of degree of coherence is departure from the set of the value of self-trapping, the beam continually expands and contracts. The evolution properties of coherent components that consist of partially coherent beams are also analyzed in detail.
