Abstract: | |
The linear and nonlinear optical properties of nematic liquid crystal thin film has been found, using a highly sensitive method known as Z-Scan technique. Z-Scan experiment was performed using a continuous wave (CW) diode solid state laser at 473 nm wavelength, and 20 mW power, the first part has been done using a close aperture, and the second part was carried out using an open aperture . The sample were prepared on glass substrates by using spin coating method. Several testing were done to study the characteristics of the sample, including X-ray diffraction, as well as Atomic Force Microscopy (AFM). Results suggest that nematic liquid crystal thin film is a promising material for third order nonlinear applications due to its large nonlinear optical properties. |
