Study of Long-term Pulsed Laser Irradiation Effect on SWCNT-Water Dispersion

In this paper, we studied the effect of long-term pulsed laser radiation from visible range on an aqueous dispersion with single-walled carbon nanotubes with a concentration of 0.005%. The dependence of the normalized transmission on time, the temperature dependence, and nonlinear optical characteristics were determined. In several minutes of irradiation, bubbles appeared in the dispersion and enlightenment was observed, i.e. increase in transmission. It was determined that an aqueous dispersion with carbon nanotubes retains its optical characteristics for 600 pulses at a laser pulses frequency of 10 Hz and power of 230 mW.
