Descriptions for the experimental details and theoretical analysis including cases where nonlinear refraction is accompanied by nonlinear absorption were presented. In these experiments, the transmittance of a sample is measured through a finite aperture in the far field as the sample is moved along the propagation path (Z) of a focused Gaussian beam. The sign and magnitude of the nonlinear refraction are easily deduced from such a transmittance curve (Z-scan). Employing this technique, the nonlinear refraction is accompanied by nonlinear absorption, it is possible to separately evaluate the nonlinear refraction as well as the nonlinear absorption by performing a second Z scan with the aperture removed. We demonstrated this method for (3GO) dye at 532 nm where two-photon absorption is present and n2 is positive. Also the optical proprieties (absorption, fluorescence spectra and the quantum efficiency) of 3GO dye solution in chloroform with different concentrations were evaluated. 2016-04-22T09:17:09Z 2016-04-22T09:17:09Z 2013 Article International Journal of Nanoelectronics and Materials, vol.6, 2013, pages 139-146 1985-5761 (Printed) 1997-4434 (Online) http://dspace.unimap.edu.my:80/xmlui/handle/123456789/41322 en Universiti Malaysia Perlis
