抄録
<jats:p>Interference of impulsively excited coherent phonons in semimetals has been studied by using a double-pulse pump–probe technique. Enhancement of the oscillation amplitude of an A1g mode is observed when the separation time of the double-pulse is matched to the period of the phonon oscillation, and a cancellation is observed when the separation time is adjusted to half the period of the phonon oscillation. The amplitude after the second pulse shows a sinusoidal dependence as a function of the separation time, and this dependence is explained in terms of a superposition of two coherent phonon oscillations. In addition, not only the A1g mode but also an Eg mode have been observed by electro-optic sampling.</jats:p>
