摘要：

The nonlinear optical properties of the poly1,4-diazophenylene-bridged-tris(8-hydroxy-quinoline) aluminum (PDPAlq(3)) solution were studied using single beam Z-scan technique with a continuous-wave Diode laser radiation at 657.2 nm with 10 Hz repetition rate. The results show that the solution of PDPAlq(3) exhibits large nonlinear refractive index (n(2)= -1.7642 x 10(-12) m(2)/W) and nonlinear absorption coefficient (beta = 1.12 x 10(-6) m/W). The negative sign of the nonlinear refractive index n(2) indicates that the material exhibits self-defocusing optical nonlinearity. The evaluation of the figure of merit (W= 1.8) shows that the solution of PDPAlq(3) is sufficient for application in all-optical switching technology. These results show that the solution of PDPAlq(3) have potential application in nonlinear optics. (C) 2010 Elsevier GmbH. All rights reserved.
