Abstract
High–purity single–wall nanotubes (SWNT) paper formed for a laser processing material. Processing performance on a pulsed–laser–beam irradiation of the SWNT paper at different process conditions was investigated. Evaluation of processed surface was conducted by SEM observation and Raman spectroscopy. Experiments results showed that SWNTs structure changed to amorphous carbon in air ambient at high power conditions. On the other hand, SWNTs structure remained at high power conditions when using Ar shielding gas. We also studied a dependence of a laser wavelength on cutting performance of SWNTs paper.
