Abstract
Third‐harmonic generation has been measured in poly(2,5‐dimethoxy p‐phenylene vinylene) thin film. The third‐order optical susceptibility, χ(3), was evaluated to be 5.4×10−11 esu at 1.85 μm wavelength. This χ(3) value is about one order higher than that for poly(p‐phenylene vinylene) and almost the same value as for poly(n‐BCMU diacetylene) which possesses the highest χ(3) value among processible (solvent castable) polymeric materials.Keywords
