Using numerical simulation, we study the influence of ratio between characteristic scales of a femtosecond mid-IR wave packet on the threshold power of filamentation and light bullets formation under condition of anomalous group velocity dispersion in transparent dielectrics. As the similarity parameter to determine the process of filament formation and light bullet creation was chosen a ratio of the dispersion length to the diffraction length of wave packet. An optimal control of light bullets’ formation can be used at the problems of environmental sensing and transportation of high-density energy in the atmosphere.
