We study the propagation of incoherent accessible solitons in strongly nonlocal media with arbitrary response function. Based on the linear propagation equation and the mutual coherence function approach, we obtain an exact analytical solution of such incoherent accessible solitons. The solitons radius is related to the total power as well as the coherence characteristics of the incoherent beam. We find that there is not a threshold for incoherent solitons exist in strongly nonlocal media because the model is linear. Evolution behaviors of the solitons width and the coherence radius are also described when the solitons undergo linear harmonic oscillation.
我们研究了具有任意响应函数的强非局部介质中不相干可及孤子的传播。基于线性传播方程和互相关函数方法，我们得到了这种不相干可及孤子的精确解析解。孤子半径与总功率以及不相干光束的相干特性有关。我们发现，在强非局部介质中不存在不相干孤子的阈值，因为该模型是线性的。当孤子经历线性谐波振荡时，还描述了孤子宽度和相干半径的演化行为。
