In this work, preparation of zinc thin films using pulsed laser deposition technique has been described. Optical absorption spectra of the films have been obtained by Spectrophotometry and their topography has been analyzed by Atomic Force Microscopy. The method of measuring the optical limiting of samples and its results for different aperture sizes are also represented. According to the obtained results, by increasing the aperture size, the critical power for observing the nonlinear effects of thin films increases. This is due to elimination of nonlinear refraction effects. In this case, increment of critical power is due to nonlinear absorption which determines the optical limiting behavior of the films.
