Figure 1. Linear and transient absorption spectra of SWNTs.

(a) Absorption spectrum of the enriched (6,5) SWNTs sample. (b) Transient absorption spectra at different pump-probe delays, with 570 nm excitation wavelength, for a (6,5) enriched SWNT sample. The probe is obtained with white light continuum, from CaF₂ for the wavelengths from 340 nm to 650 nm and from sapphire for wavelengths from 850 nm to 1100 nm.
