An effect of group velocity dispersion in transparent dielectrics and laser impulses’ power on laws of the formation of light bullet sequence with high spatiotemporal light field localization was numerically studied in work. It was found that the number of light bullets in a wave packet depends on the relation between parameters of similarity, which determine the pulse self-compression under conditions of anomalous group velocity dispersion and self-focusing of laser beam. It is shown that peak intensity in light bullets doesn’t depend on initial intensity of pulse and increases with increasing of photo-ionization process’ multiphoton order, exceeding 100TW/cm2. Obtained results could be generalized to the problem of transportation in atmosphere high-fluence energy by Mid-IR laser pulses.
