研究了非线性介质中部分相干光脉冲（PCLP）的准稳态（QSS）自聚焦。给出了非线性介质中 PCLP 自聚焦 QSS 的解析公式（例如光束宽度、空间相干宽度和焦距）。详细研究了空间相干性对焦距和焦点移动的影响。特别是，我们发现PCLP比完全相干光脉冲在避免材料光学损伤方面更有优势。
The quasi-steady-state (QSS) self-focusing of partially coherent light pulses (PCLPs) in nonlinear media is studied. The analytical formulas of the QSS self-focusing of PCLPs in nonlinear media (e.g., the beam width, spatial coherence width, and focal length) are presented. The effect of spatial coherence on the focal length and focus moving is investigated in detail. In particular, it is found that a PCLP has more advantages to avoid the optical damage of materials than a fully coherent light pulse.
