摘要

In this paper, we performed the femtosecond time-resolved X-ray diffraction on the 60-fs laser irradiated a CdTe single crystal and detected the coherent longitudinal optical (LO) phonon (5.07 THz) at Brilliuon zone center. The coherent LO phonon is also confirmed by using an optical reflectivity measurement
