Direct acoustic phonon excitation by intense and ultrashort terahertz pulses Academic Article

abstract

• We report on the direct and resonant excitation of acoustic phonons in an AlGaAs intrinsic semiconductor using intense coherent and single cycle terahertz pulses created by two-color femtosecond laser pulse filamentation in air. While the electrons are left unperturbed, we follow the lattice dynamics with time-delayed optical photons tuned to the interband transition. 2010 American Institute of Physics.
