The ultrafast dynamics study of photoexcitations in semiconducting and metallic single-walled carbon nanotubes (SWNT) was presented. Various pump-probe wavelengths and intensities were used in studying the femtosecond dynamics of photoexcitations. The ultrafast response in the SWNTs was dominated by confined excitons and charge carriers with subpicosecond dynamics. The analysis of exciton excited state absorption band and multiphoton absorption resonance revealed that the transitions between the subbands were allowed.
