数值研究了群速度法向色散对光脉冲自聚焦的影响。当超过临界功率时，观察到场包络的时间分裂，沿着与脉冲的空间锐化的中心部分的衍射。色散显著增加了短脉冲持续时间的自聚焦阈值。
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.
