Practical analysis of laser beam parameter in Z-Scan technique

Abstract

The z-scan is an important optical technology that is used to diagnose the optical behavior of different materials and optical elements and to verify their parameters by defining their linear and non-linear optical properties, this technique is based on the principle of the interaction of the laser beam with the material within tunable ranges of power, During the research, this technique was employed in a research and experimental manner to determine its capabilities and record its ability to be a database that can be adopted in future research in this field. The solid-state laser type (Nd: YAG) continuous wave (CW) 100mW @ 1064 nm was calculated intensity of the beam, depending on the approved engineering distribution was calculated intensity of the laser beam were observed harmony wonderful ability within the ranges of the optical axis can be employed in the experiments to determine visual qualities of linear and nonlinear materials.
