Using numerical modeling, the possibility of forming (2D+1) short-period (3—5 oscillations under the envelope) light bullets in non-centrosymmetric media with the second harmonic at the presence of phase and group velocities mismatches is shown. It is demonstrated that cubic nonlinearity does not prevent the formation of space-time solitons only up to certain intensity values.
