| Abstract: | A model for measurement of nonlinear optical properties by scanning laser beam distortion has been studied. The cubic nonlinear susceptibility used has both absorptive and refractive components. We describe the experimental apparatus and present a comprehensive theoretical analysis including cases where linear and nonlinear absorption are combined. The practical measurement procedures are discussed for these parameters. |
