| Resumo≠ | The Z-scan technique is an experimental method for measuring nonlinear optical properties of materials, particularly third-order susceptibility and nonlinear absorption. Developed by Sheik-Bahae, Hagan, and Van Stryland in 1990, Z-scan uses a tightly focused laser beam and moves the sample along the beam propagation axis (z-axis), recording transmission variation to deduce nonlinear refraction and absorption coefficients with high sensitivity. | Fourier optics is a mathematical framework that analyzes optical systems and phenomena using Fourier transforms and frequency-domain methods. Grounded in Joseph Fourier's 1822 work on heat diffusion and Ernst Abbe's microscopy theory, this approach decomposes optical fields into plane waves or spatial frequencies, revealing how optical systems manipulate and filter these components to produce images and transmit information. |
