Time Resolved Spectroscopy Facility for the Study of Nonlinear Optical Properties of Semiconducting Polymers.

Abstract

We have measured the third order susceptibility associated with frequency tripling the fundamental of a Nd:YAG laser in various samples of polyacetylene. By measurement of the amount of third harmonic power reflected from a trans-polyacetylene sample relative to that from a sample of intrinsic silicon, we have determined the magnitude of Xv(3). (all indices parallel to the chain direction) to be XII(3) = 9 + or - x 10 to the -10th esu. Studies on oriented samples indicate that XII(3) dominates all other components of the XII(3) tensor, consistent with the large nonlinear susceptibility being due to the conjugated pi-electron backbone. We have also measured third harmonic generations in cis-rich polyacetylene samples.
