Abstract: (1563 Views)
In this paper ,QYPDLC-142 Nematic Liquid Crystal (NLC) doped with different percentages of 1%, 2%, 3%, of Single-Wall Carbon Nanotube(SWCNT) was prepared. The third order nonlinear refractive index of cells 
prepared by different percentages was investigated using close z-scan technique. The laser used in this study was the Nd:YAG laser at 532 nm and power 5 mw. The results indicate that addition of a single-wall carbon nanotube significantly increases the nonlinear refractive index of the nematic liquid crystal QYPDLC-142. For the doped liquid crystal cell with 1% of carbon nanotube obtained the highest refractive index than other concentrations.
