TLDR
Low-power phase conjugation of azobenzene-compound-doped poly(methyl methacrylate) films was studied and it was shown that this kind of polymer has appreciable third-order optical nonlinearity.Abstract:
Push–pull azobenzene compounds were synthesized by the diazocoupling reaction, and low-power phase conjugation of azobenzene-compound-doped poly(methyl methacrylate) films was studied with a He–Ne laser at 632.8 nm. It is shown that this kind of polymer has appreciable third-order optical nonlinearity, with a χ(3) of approximately 10−4 esu in the tail of absorption.read more
