Paper Abstract

Phonon coherent excitation can be ascribed to an impulsive or a spectral mechanism, when dealing with ultrashort pulses. Contrary behaviors, that depend on wave vector matching conditions, are revealed and selected by a specific detection arrangement. A spectral analysis of the signal confirms this findings.
