Abstract
The nonlinear refraction and nonlinear absorption of ZrO2 thin films doped with CdS and ZnS nanoparticles and various metals were investigated using the Z-scan technique. The structural properties of these films (TEM, EDX) were compared with their optical and nonlinear optical characteristics. The values of nonlinear refractive index of these films were measured to be of the order of at a laser intensity of 9 ? 109?W?cm?2. Sign variations of ? of ZrO2:CdS(Cr) and ZrO2:ZnS(Mn) films due to fifth-order nonlinearities were observed and analysed using the intensity-dependent Z-scan studies of nonlinear optical parameters.
