Investigation of the Nonlinear Properties of Carbon Nanomaterials for Thresholding of Powerful Laser Radiation

The nonlinear optical properties of dispersed carbon nanotube-based (CNT-based) media (dispersions) and solutions of polymethine dye PD-7098 and dicyanomethylenepyran dye DCM-627 have been studied. Values of the threshold intensity for nonlinear processes and nonlinear absorption coefficient were ca...

Zusammenfassung:The nonlinear optical properties of dispersed carbon nanotube-based (CNT-based) media (dispersions) and solutions of polymethine dye PD-7098 and dicyanomethylenepyran dye DCM-627 have been studied. Values of the threshold intensity for nonlinear processes and nonlinear absorption coefficient were calculated. All CNT-based dispersions displayed a threshold effect, while in dyes no threshold effect was found.
