Self phase modulation of a Gaussian laser beam through a non linear thin film

After some numerical experience, we developed a technique allowing the fast computation of an integral appearing in the mathematical study of the diffraction rings produced by the self phase modulation of a Gaussian laser beam through a non linear thin film. The results obtained by means of a simple microcomputer (IBM-PC) are shown to may be used for the deduction of the non linearity properties of the film.
