Linear Electron-Phonon Interaction in Dye-Doped Polymers: Boson Peak Frequencies in Polymers,

Abstract

This talk presents a review of our recent experimental results on femtosecond accumulated photon echo in dye-doped Polymers. The aim of this research is to clarify the parameter that is most important n affecting seriously the linear electron-phonon coupling in these samples, and to find the materials which have extremely weak linear electron-phonon coupling. The latter research is needed for the improvement of the PHB memory materials. We have so far demonstrated experimentally that Fourier-transform spectroscopy based on the femtosecond accumulated photon echo is most useful for these studies. Furthermore, the detection sensitivity for the accumulated photon echoes has been improved significantly with the use of the phase modulation technique.
