Scientific paper

We measured third-order nonlinear susceptibility (χ(3)) spectra in semiconducting single-walled carbon nanotubes (SWNTs) by the Z-scan method. |Imχ(3)| is remarkably enhanced under resonant excitation to the lowest interband transition, reaching 4.2×10-6 esu and 1.5×10-7 esu in SWNTs grown by the laser ablation and HiPco methods, respectively. A comparison of the transient absorption changes evaluated by degenerate and nondegenerate pump-probe measurements suggests that the resonant enhancement of |Imχ(3)| is dominated by a coherent process rather than by saturation of absorption.
