  2. Z-scan technique - Wikipedia

    en.wikipedia.org/wiki/Z-scan_technique

    In nonlinear optics z-scan technique is used to measure the non-linear index n 2 (Kerr nonlinearity) and the non-linear absorption coefficient Δα via the "closed" and "open" methods, respectively. As nonlinear absorption can affect the measurement of the non-linear index, the open method is typically used in conjunction with the closed method ...
