Closed-Aperture Z-Scan Analysis for Nonlinear Media with Saturable Absorption and Simultaneous Third- and Fifth-Order Nonlinear Refraction
Figure 5
(a) Open-aperture Z-scan at (a) 0.6, (b) 1.2, and (c) 1.8 GW/cm2 for a film sample with 0.91 vol.% CdSe QDs. (b) Transmittance change at as a function of input intensity . The best fittings correspond to the SA (red) and TPA (black) models, respectively.
