摘要

研究了强多频光束在克尔非线性作用下的传输。在谐振和非谐振两种情况下，得到了具有混合拓扑电荷的特定频率比孤子的数值解。这些发现有助于更好地理解自相似多色坍缩的临界功率，并可能导致新型的长丝传播。

Twisted multi-color optical self-focusing in a nonlinear medium

We study the propagation of intense multi-frequency optical beams under the effect of Kerr nonlinearity. Soliton solutions with mixed topological charges were obtained numerically for certain frequency ratios in both resonant and non-resonant regimes. These findings lead to a better understanding of critical power for self-similar multi-color collapse and could lead to novel types of filament propagation.
