Spectral broadening of femtosecond optical vortices under filamentation in a medium with anomalous group velocity dispersion

Filamentation of femtosecond optical vortex at central wavelengths of 1800 nm and higher in fused silica and fluorides was experimentally and numerically studied. The features of broadening of frequency and frequency-angular spectra are considered.
