摘要：

The nonlinear refraction and nonlinear absorption of ZrO2 thin films doped with US 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 gamma similar to 3.5 x 10(-13) cm(2) W-1 at a laser intensity of 9 x 10(9) W cm(-2). Sign variations of gamma 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.
