Abstract

Third order nonlinear optical coefficients were obtained for a new chromophore 4(4'-N,N'- dimethyl amino phenyl)-1-, 1-bis(trifluoromethyl sulfonyl)-1,3-butadiene (MAG) doped in poly(ethyl)methacrylate (PEMA). The real and imaginary parts of the third order response were investigated at wavelengths close to and far from the resonant absorption maximum by quadratic electro-optics and quadratic electro-absorption (QEA) techniques. From these data real and imaginary parts of the Kerr coefficient are obtained. At room temperature the QEA measurement was also used to determine the ratio of the two contributing tensoral components of the third order response at wavelengths near the resonant absorption maximum. The tensor ratio suggest that an electronic mechanism dominates the third order response at room temperature for the MAG/PEMA system.
