Nonlinear effects in photoinduced nanomovement of carbazole-based azo-polymers

Abstract

This paper describes synthesis, characteristics and experimental observation a new nonlinear optical characteristics new azopolymer based on poly-n-epoxypropyl carbazole (PEPC) and Disperse Orange 3 under the influence of a highintensity laser beam. The regularities in the formation of surface microstructures by the action of a focused Gaussian beam on the film of the synthesized polymer are shown. The dependence of the formation of the microstructure with increasing beam power density is studied. Nonlinear topographic effects arising in the formation of microstructures by beams with linear and circular polarization are described. The anisotropic nanoscale polymer movements were demonstrated for linearly polarized laser beam irradiation.
