The third-order nonlinear optical properties of the N-6-hydroxy-hexyl-4-azophenyl-carbazol have been investigated both theoretically and experimentally. Using Z-scan method with a femtosecond laser (440[Formula: see text]nm, 190[Formula: see text]fs), the third-order nonlinear optical properties of the N-6-hydroxy-hexyl-4-azophenyl-carbazol were determined. The second-order hyperpolarizability [Formula: see text] of the experiment result was found to be [Formula: see text][Formula: see text]esu. We have also calculated the second-order hyperpolarizability based on the sum-over-states (SOS) method. The theoretical value was in accord with the experiment result. The result showed that the N-6-hydroxy-hexyl-4-azophenyl-carbazol was one of the promising third-order nonlinear optical materials.

This study reports the results of direct implantation of symmetry into calculations of carbon nanotubes (CNTs) second order nonlinear optical properties. In particular, it is described a code based on sum over states (SOS) method and suitable to evaluate quantitatively the frequency dependence of CTNs first hyperpolarizability. The main advantage of performing SOS calculations with symmetrized eigenfunctions relies on the direct identification of the essential channels giving a contribution to first hyperpolarizability. As an explicative example the results of calculation for the (4,1) chiral topology are reported and the transitions responsible for resonant enhancement are identified.
