Paper Abstract

The Z-scan technique is a popular method for measuring degenerate optical nonlinearities using a single laser beam. In cases where nonlinear refraction is accomplished by storing nonlinear absorption, we report an accurate analytic method for extracting nonlinear refraction from the closed aperture Z-scan transmittance curve with the aid of the open aperture Z-scan transmittance curve. This method possesses very high accurayc, especially, in the presence of strong nonlinear absorption and/or for the larger size aperture. This method is also demonstrated on a solution of Pd(mpo)2 by the experiment.
