Closed-Aperture Z-Scan Analysis for Nonlinear Media with Saturable Absorption and Simultaneous Third- and Fifth-Order Nonlinear Refraction
Figure 6
Closed-aperture -scan at GW/cm2 for the same film sample as that shown in Figure 5. In Figure 6(a), solid curves correspond to the least-squares fit of the theoretical formulae for a medium possessing the third-order nonlinear refraction without (black) and with (red) the fifth-order nonlinear refraction in the absence of saturable absorption of a homogeneously broadened type. In Figure 6(b), solid curves correspond to the least-squares fit for a medium possessing the third-order nonlinear refraction without (black) and with (red) the fifth-order nonlinear refraction in the presence of saturable absorption of a homogeneously broadened type.
