Femtosecond Studies of Dephasing and Phase Conjugation With Incoherent Light

摘要: The fast response of electroactive polymers as nonlinear optical materials is one the main features which are attracting attention increasing number researchers. Especially, large nonlinearity organic polymeric systems containing conjugated π-electron structures expected to have times in femtosecond regime because their purely electronic origins. Some them regarded attractive candidates for ultrafast processing devices, and a switching time 0.1 ps suggested an switch utilizing polydiacetylene material.1 Studies most simply performed by transient four-wave mixing, nonlinearities several been studied mixing using short pulses.2–6 In this article, we describe picosecond measurements relaxation three types temporally incoherent light instead pulses.
