We evaluate the modes for non-Schell-model sources whose degrees of spectral coherence depend on the difference of the special function values of the position coordinated of two points. It is shown that such sources modulated by various function possess different spatial coherence properties, and cause them to produce the self-focusing fields with different characteristics. The results suggest a convenient method for modeling novel classes of partially coherent self-focusing optical fields.

产生自聚焦场的特殊相关模型源

我们评估非 Schell 模型源的模式，其光谱相干程度取决于两点坐标位置的特殊函数值的差异。结果表明，这些由各种函数调制的源具有不同的空间相干特性，并导致它们产生具有不同特性的自聚焦场。结果表明了一种方便的方法来模拟新型部分相干自聚焦光场。
