| Popis: | Quantitative measurements of the nonlinear refractive index coefficient ( n 2 and the third-order nonlinear susceptibility (χ (3) ) for a solution of 7',7'-dicyano-7'-apo-β-carotene (DCAC) in hexane have been measured at different concentrations. The measurements have been performed by both the self-trapping and self-phase modulation techniques using a cw Ar + laser. The results show that DCAC has a relatively large nonlinearity, attributed to a thermal mechanism, with n 2 of the order of 10 9 times that of CS 2 . |
