Paper Abstract

Recent femtosecond time-resolved pump-probe experiments have detected large amplitude oscillations due to coherent phonon generation in the reflection (R) from various materials). These oscillations show only vibrational modes with A1 symmetry, even though other Raman-active modes of comparable Raman cross section exist. Experimental results showing the properties of this phenomena and a model that explains many of the experimental phenomena are presented.
