Abstract
The influence of normal group-velocity dispersion on the self-focusing of light pulses is numerically studied. Temporal splitting of the field envelope is observed when the critical power is exceeded along with diffraction of the spatially sharpened central part of the pulse. Dispersion increases considerably the self-focusing threshold for short pulse durations.Keywords
