Description:
Author(s): Kazutaka G. Nakamura, Yutaka Shikano, and Yosuke Kayanuma We investigated the coherent phonon generation mechanism by irradiation of an ultrashort pulse with a simple two-level model. Our derived formulation shows that both impulsive stimulated Raman scattering (ISRS) and impulsive absorption (IA) simultaneously occur, and phonon wave packets are generated… [Phys. Rev.
