Abstract
Ultrafast optical response in polydiacetylenes and polythiophense was investigated by femtosecond time-resolved absorption spectroscopy. Several nonlinear optical processes, i.e. hole burning, Raman gain, and induced-frequency shift, were observed and the third-order nonlinear susceptibilities were determined. The ultrafast relaxation dynamics following after the photoexcitation was investigated and the formation and relaxation of self-trapped exciton was observed
