Resumen:
The second-order nonlinear optical susceptibilities ?(2) of two isomeric polymers containing an azo dye, Disperse. Red 19, were determined by the first-order electroabsorption spectroscopy (EAS), and compared with values previously obtained by SHG measurements. The para-polymer was found to have higher susceptibility than the corresponding meta-polymer. ?(2) were found to be 5-6 × 10-8esu, which are comparable to those obtained by the Maker Fringe method. © World Scientific Publishing Company.
