Photoinduced Anisotropy in Azopolymer Studied by Spectroscopic and Polarimetric Parameters

Abstract

We discuss methods for synthesis and fabrication of photosensitive thin azopolymer films. Spectroscopy of films presents information as about nonactinic and recording wavelengths as a for refraction index calculations by Swanepoil method. Photoinducing of anisotropy was done by blue laser. The resulting polarimetric light parameters produced by photoinduced anisotropy measured at nonactinic He-Ne red wavelength. For this aim a polarimeter was applied. Kinetics of a value of photoinduced anisotropy, azimuth and ellipticity of light passed through films were investigated.
