Abstract

The Z-scan measurement technique is a scanning method used to know the non-linear optical behavior due third order process in different materials, some of these behaviors are: as saturable absorption, reversible and non-reversible absorbers, absorption of more than one photon, among others. This technique is based on the displacement of the sample in the direction of propagation (Z) of a laser light beam. In this work the study of the nonlinear properties of three samples was carried out through this technique using a continuous wave laser, with Gaussian profile, and emitting at λ = 1550 nm, the samples used were: ethanol, acetone, and distilled water. Nonlinear absorption and nonlinear refraction were observed for the three samples.
