AB  - We have investigated optical limiting properties of liquid crystal doped by (CuCl<sub>2</sub>) nanoparticles in ethanol solvent with different concentrations (2, 4 and 6)H10<sup>-5 </sup>M. The measurements were performed by Z-scan technique using Continuous Wave (CW) diode solid state laser at (457 nm) wavelength and (84 mW) power. The sample shows very good optical limiting behavior arising from nonlinear refraction. The results showed that the threshold of optical capacity reduction was inversely proportional to concentration which meant that optical selection characteristics were better with increasing concentrations, the result implied that all samples prepared can be used as a potential medium for various optoelectronic applications including that in optical limiting.
