- The nonlinear optical properties of nematic liquid crystal material have been studied at different concentrations using Z-Scan technique. Experiments are performed using continuous wave (CW) diode solid state laser at 473 nm wavelength and 20 mW power. The nonlinear absorption coefficient β is calculated using open aperture Z-Scan data, while its nonlinear refractive index n2 is measured using the closed aperture Z-Scan data. In this work, six concentrations were prepared for (Di-Cinnamylidene Benzidine), these concentrations were (9×10-5, 8×10-5, 7×10-5, 6×10-5, 5× 10-5 and 4×10-5)M. The optical absorption and transmission spectra for these concentrations were measured by using UV-VIS spectrophotometer. Our results show that the nonlinearity are changed significantly with concentrations, in addition, the optical limiting behavior has been studied. The results confirmed the capability of the sample to be used as optical limiter device.
