Abstract: Sets of steady-state localized temporal structures of radiation with a duration comparable with the period corresponding to the frequency of atomic transitions are found for a medium consisting of active (with a pump) and passive (without a pump) atoms with homogeneous broadening. The velocity of motion of these structures takes discrete values depending on the number of field spikes and the number of oscillations of the polarization of the active and passive atoms within the intervals between the field spikes.
