Analysis of polarization degree of the light emergent from the nanoparticles suspensions

摘要

In this work I have determined the degree of polarization, with a polarimeter setup, of a laser beam which passes through nanoparticles suspension. The main idea is to see how the degree of polarization of the laser is modified after it passes through different nanoparticle suspension media. With this setup we can find the Stokes parameters (S1, S2 and S3) and determinate the degree of polarization. The Stokes parameters, which characterize the state of polarization, are provided as analog output powers. The samples are different metallic nanoparticles in suspension with different dimensions and concentrations.
