| dc.description.abstractEn | The third order optical non-linearities χ(3) of some excited diphenyl-polyene derivatives (t-stilbene, 1,4 diphenyl-butadiene, 1,6 diphenyl-hexatriene, 1,8 diphenyl-octatetraene) have been studied using Degenerate Four Wave Mixing (DFWM) and Optical Kerr Effect (OKE) on a sub-picosecond time-scale. Strong enhancements of χ(3) between ground and excited states are observed for some compounds and discussed taking into account the symmetry of excited states and resonance conditions. The dynamics of χ(3) has been measured and may show fast or slow regimes, depending on the compound. The spectral dependence of the real and imaginary part of the optical non-linearity have been measured. | |
