Popis: | A large photoinduced reversible change of third-harmonic generation in azo-dye polymer thin films was recently observed. In this work, the microscopic interpretation of this phenomenon is given. The model presented is based on an angular hole burning and molecular reorientation due to trans-cis photoisomerization of azo-dye molecules. |
