Photoinduced Nonlinear Absorption and Third Harmonic Generation Variations in Azo Polymer Thin Films

Not Accessible

Your library or personal account may give you access

Abstract

The third harmonic generation (THG) and nonlinear transmission (NT) were used to probe the change of χ(3) in azo-doped polymethylmethacrylate (PMMA) thin films. The observed phenomena can be interpreted by a microscopic model based on angular hole burning (AHB) and angular redistribution (AR) mechanisms of photoisomerization effect. In this experiment, the pumping effect on the THG and NT at different polarization directions is investigated.
