Schematics of the optical layouts for two-tint pump-probe measurements of (a) TDTR and (b) TRIARS.
(a) Spectral intensities in the two-tint pump-probe measurements of TDTR. The output of the laser is sliced at either side by two optical filters to create the pump and probe beams. A third optical filter blocks diffusely scattered pump light from reaching the detector. The solid and dashed lines are the spectral intensities before and after the third optical filter, respectively. (b) Spectral intensities in the two-tint pump-probe measurements of TRIARS.
Time correlations of the pump and probe optical pulses in the two-tint pump-probe measurements of (a) TDTR and (b) TRIARS. The solid and dashed lines are the pump-probe correlations without and with optical filters, respectively. The FWHM of the pump-probe correlation without filters is , and the correlations with filters in the measurement of TDTR and TRIARS are and , respectively.
Anti-Stokes Raman spectra for arc-discharge carbon nanotubes created by both pump and probe optical pulses. Raman intensity is normalized by the integration time, power in the probe beam and spectral width of one charge coupled device pixel.
