Excitation of Coherent Phonons and Plasmons in InSb by Impulsive Raman Scattering

Abstract

Electromagnetic radiation is emitted by the vibrational and collective model of an opaque solid as the result of impulsive stimulated Raman scattering. Raman scattering of near-infrared femtosecond laser pulses produces coherent longitudinal optical phonon and plasmon oscillations in the semiconductor InSb. These oscillations radiate into free space at THz frequencies and are directly detected.
