Abstract :
We present experimental and numerical results using different characterization techniques in order to obtain the third order nonlinear optical coefficients. Starting with the classical Z-scan method for materials having low optical quality, we describe also a spatially resolved Mach-Zehnder interferometry system as well as a simple imaging method using a 4f setup with a phase object at the entry. Some of these techniques are particularly appropriate to study fragile materials because the results can be obtained with a limited number of laser shots. In all cases, the nonlinearities are obtained by analyzing the intensity profiles of the image acquired with a CCD camera after nonlinear filtering through the material in a focal plane of a converging lens. Advantages and drawbacks are summarized for each technique.
