Abstract :
Summary form only given.Ultrafast optical dephasing measurements were performed on thin films of the oxazine dye Nile Blue in poly-[vinylalcohol] (PVOH). The experimental technique used two-beam, time-delayed degenerate four-wave mixing (DFWM) with incoherent light. Small time delay oscillations in the DFWM signal were observed under the conditions that the sample was at relatively high temperatures (between 200 K and room temperature) and the measurements were made on the blue side of the Nile Blue inhomogeneous distribution.
