nonlinear optical susceptibility

Synthesis and Characterization of Dye-Doped Polymer Films for Non-linear Optical Applications

In this work polymer nonlinear optical (NLO) materials in the form of thin films based on 3,7,3’,4’-tetrahydroxyflavone and diglycidyl ether of bisphenol A were obtained and investigated. It was found that the influence of the chromophore concentration on values of the macroscopic NLO susceptibilities (χ(2) of doped polymer films has extreme character. The maximum value of χ(2) is 6.11 pm/V at the concentration of dopant 20 wt %.
