The paper presents experimental studies of physical processes and conditions for generate high-directional white-light supercontinuum in visible range. It was shown that it occurs in filamentation area and postfilamentation channel under different spectral broadening mechanisms step by step. Experimentally shown that these phenomena can be realized under aberration focusing.
Keywords: femtosecond laser, white-light supercontinuum, simulated Raman scattering, coherent anti-stokes Raman scattering, Four-wave mixing.
