摘要
We show both theoretically and experimentally by degenerate four-wave mixing that the combined processes of optical rectification and the linear electro-optic effect contribute to the large effective third-order susceptibilities [14 chi((3))(CS2)] of the organic salt 4-N, (N) over cap-dimethylamino-4'-N'-methylstilbazolium toluene-p-sulfonate (DAST). Furthermore, the knowledge of the cascaded contributions was used to determine absolute values of the third-order susceptibilities as well as their sign.
