Abstract

We investigate the third-order nonlinear optical property of a range of [beta]-carotene homologues, which have different numbers <i>(n)</i> of conjugated C=C double bonds from <i>n</i>=7 to 15, by using third-harmonic generation Maker fringe technique. The results clearly show that there is a remarkable enhancement of the third-order optical nonlinearity when <i>n</i>=15, which is a four fold increase compared with <i>n</i>=11 (i.e. -carotene).
