Resonant medium radiation, initiated by an ultra-short light is considered. It is shown that under such superluminal excitation in the spectrum of medium radiation there are new frequencies, in addition to the resonance frequency of the medium oscillator. They depend on the spatial frequency oscillator distribution of and the angle of observation.
