Abstract: Primary photon echo in polymer films doped with dye molecules is investigated. Spectral properties and temporal structure of echo-response under conditions of noncollinear excitation are considered. The conditions of satellite formation and spectral switching of echo-signal frequency are analyzed.

Keywords: photon echo, inhomogeneous broadening, dye-doped polymers, satellites, frequency shift, diffraction, spectral switching.
