In these mediums, the nonlinear refraction is strongly dependent on the detuning from the optical resonance frequency and therefore nonlinear effects can be observed at low laser intensity. The response of these systems is expressed by the third-order nonlinear susceptibility, which appears as an intensity-dependent term in the refractive index of the medium. Z-scan is one of the most accurate experimental methods for measuring of the nonlinear refractive index. In this paper, in order to predict the dependence of the nonlinear refractive index on the factors involved in the Z-scan technique, we have used a semi-experimental method to simulate the transmitted intensity thorough the rubidium vapor for the positive and negative detunings of the resonance frequency and the results have been analyzed. }, URL = {http://opsi.ir/article-1-1445-en.html}, eprint = {http://opsi.ir/article-1-1445-en.pdf}, journal = {Accepted and Presented Articles of OPSI Conferences}, doi = {}, year = {2018} }
