| Abstract | ||
| LiNbO3 thin films were prepared on quartz substrates by sol-gel process using Lithium carbonate (Li2CO3) and niobium oxide. Several testing were done to study the characteristics of the sample,including X-ray diffraction,as well as transmission and digital holographic microscope(DHM).We have employed Z-Scan technique to study the nonlinear optical properties, represented by the nonlinear refractive index and nonlinear absorption coefficients of a thin film. Z-Scan experiment was performed using a CW Nd:YAG and Nd:YVO4 lasers in two parts ; the first part has been done using a close aperture at two wavelengths(532 nm and 1064 nm) and the second part was carried out using an open aperture at two wavelengths(532 nm and 1064 nm). | ||
