Abstract
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.
