摘要

We consider Cherenkov-type radiation from inhomogeneous periodic resonant medium excited by an ultrashort pulses of light. It is shown that if the velocity of the propagating excitation is greater (lower) then the velocity of light in vacuum c, a new Doppler-like frequency appears in the spectrum of the medium response. This frequency depends on the medium density distribution and on the observation angle. Possible applications of the effect are discussed.
