Abstract : During the three years of this grant, progress was made on several topics related to coherent phonons: displacive excitation of coherent phonons; optical acoustic phonon coupling in glass fibers; carrier-phonon scattering in semiconductors; and coherent optical phonon generation in superconducting C60. The progress in each is reviewed in the Technical Report below. More detailed discussion and experimental details are given in the references to the journal articles and PhD theses that resulted.
