Visible laser attenuation characteristics using various polymeric nanocomposites

Abstract

The attenuation characteristic of a semiconductor laser and green laser beam power with various polymer nanocomposites including PbS, TiO2, V2O5, and CuO are investigated experimentally. Various polymeric nanocomposites with the same concentration of different nanoparticles were prepared using a solution casting technique. The distance between the sample and detector as well as the sample and laser source, and the laser beam incident angle on the surface of the sample are found to be important factors to obtain robust measurements of the attenuation of the semiconductor and green laser beam power. The nanocomposite thin film doped with CuO has more laser beam power attenuation compared to the other prepared nanocomposite thin films. Polymer nanocomposites have various applications, e.g., cut-off laser filters, optical limiting laser, and laser beam power attenuation.
