 | Vardeny, Zeev Valentine | Femtosecond dynamics of the nonlinear optical response in polydiethynylsilane | We have measured the femtosecond dynamics of the nonlinear optical response xc3' in polydiethynylsilane ( C4H2SiBu2)x, a novel class of r-conjugated polymers incorporating Si, using degenerate four-wave mixing and photoinduced absorption techniques. In resonance conditions at 620 nm we found x (3) ... | Polydiethynylsilane; Femtosecond dynamics; Nonlinear optical response; Pi-conjugated polymers | 1991 |
