Abstract
We discuss the possibility of the generation of coherent packets of monochromatic acoustic waves in the far-infrared frequency range by electromagnetic radiation. The University of California, Santa Barbara free-electron laser could be used to excite resonantly transverse acoustic phonons in periodic space-charge layers formed in modulation-doped GaAs–Ga1−xAlxAs superlattice structures. The conversion efficiency for the process (acoustic power/incident electromagnetic power) is estimated to be of the order of 10−3 at 0.25 THz.
