Abstract
Analytical expressions for velocities of the center of mass and dispersive spreading of optical pulses with a small number of electromagnetic field oscillations in dielectric media have been obtained. For some typical time profiles of input pulses, these expressions are reduced to elementary functions of dispersion characteristics of the medium, central frequency of the pulse, and initial number of oscillations in it. It is shown that the duration of a terahertz pulse of one full-wave oscillation of the field can increase by a factor of \(\sqrt 2 \) when propagating in a dielectric to distances of only three central radiation wavelengths. For pulses of two full-wave oscillations of the field of the near-IR spectral range, the frequency of the zero group dispersion in a dielectric can shift by more than 200 nm.
