Background: In this work, the experimental behavior observed in the z-scan curves of a sample of bleached photographic film for different incident powers is theoretically modeled.
Methods: Two models are modified in order to fit the experimental z-scan curves. The Focal Length Dependent on a power of the beam radius (FLD) model and the Nonlocal (NL) model.
Results: As a result of the fitting, it is not possible to fit the experimental results considering only one contribution during the z-scan experiment.
Conclusion: The results demonstrated that two contributions were needed to reproduce completely the experimental z-scan curves in both models.
Key words: Nonlinear optics / Z-scan / Photographic film
