Paper Abstract
The optical characterization of nonlinear media through the Z-scan technique considers initially a thin
medium (with a thickness much less than the beam depth of focus). It has been observed that increasing the
thickness of the medium the transmittance increases, this means that n2 increases, for this reason we will
present a numerical model to determinate the minimum thin and the maximum thick medium limit. A thin
medium is considered as a thin lens with focal length F1 and a thick medium can be regarded as a set of such
thin lenses set with focal lengths F2, these lenses are contained in a medium whit a refraction index different
than air. This analysis is made through Matlab using the theory of Gaussian beams, ABCD matrices and the q
parameter, elementary theory in the development of this work, where the main feature of this model is that the
nonlinearity type of the medium is considered as an integer constant in its focal length3. We present the
graphs obtained from Z-scan for thick medium with both thermal and Kerr nonlinearities.
