Microwave treated water soluble and amide functionalized single walled carbonnanotubes have been investigated using femtosecond degenerate pump-probe andnonlinear transmission experiments. The time resolved differential transmissionusing 75 femtosecond pulse with the central wavelength of 790 nm shows abi-exponential ultrafast photo-bleaching with time constants of of 160 fs (130fs) and 920 fs (300 fs) for water soluble (amide functionalized) nanotubes.Open and closed aperture z-scans show saturation absorption and positive(negative) nonlinear refraction for water soluble (amide functionalized)nanotubes. Two photon absorption coefficient,beata ~250 cm/GW (650 cm/GW) andnonlinear index, gamma ~ 15 cm^2/pW (-30 cm^2/pW) are obtained from thetheoretical fit in the saturation limit to the data for two types of nanotubes.
