In this paper, we focus on our recent study on vibrational coherence and coherent phonon of Cs or K adsorbed on Pt(111) by using femtosecond time-resolved second harmonic generation. The dynamics of vibrational coherence of alkali-Pt stretching mode is observed in time-domain and the mechanism of vibrational dephasing is discussed. We also study an effect of pulse shaping on a mode-selective coherence excitation.
