FIG. 1.

(Color) Schematic illustration of the LARCS method. The SWNTs with specific chirality that are at resonance with the energy of the excitation laser beam are selectively removed after the intense laser irradiation.

FIG. 3.

Raman spectra of SWNTs before and after laser irradiation of line at (a) high power density of for and (b) mild power density of for . The Raman spectra are measured with the 457.9, 488.0, and lines of Ar-ion laser at the same spot, respectively.

FIG. 4.

Average intensity ratio of the RBM signals from SWNTs after laser irradiation of line to those before the laser irradiation as a function of Raman excitation energy.
