研究目的
Investigating the effect of long-term pulsed laser radiation on the aqueous dispersion of single-walled carbon nanotubes and its implications for optical limiters.
研究成果
The aqueous dispersion of SWCNTs exhibits strong nonlinear properties initially but shows increased transmission after prolonged irradiation. It retains optical properties for approximately 600 pulses under the given conditions, suggesting potential applications in laser protection devices.
研究不足
The study is limited to a specific concentration of SWCNTs and laser parameters. The findings may not generalize to other conditions or materials.
1：Experimental Design and Method Selection:
The study involved exposing an aqueous dispersion of SWCNTs to pulsed laser radiation to observe changes in optical and thermal properties.
2：Sample Selection and Data Sources:
An aqueous dispersion of SWCNTs with a concentration of
3：005% was used. List of Experimental Equipment and Materials:
Nd: YAG laser, cuvette, sensor, pyrometer, thermal imager, spectrophotometer.
4：Experimental Procedures and Operational Workflow:
The laser irradiated the cuvette for 75 minutes, with measurements of incident and transmitted radiation power, temperature, and thermal imaging taken throughout.
5：Data Analysis Methods:
Analysis of normalized transmission, optical density, and temperature changes over time.
