Z-scan
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.
