Abstract
Push-pull azobenzene compounds were synthesized by the diazocoupling r eaction, 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-orde r optical nonlinearity, with a ((3)(chi)) of approximately 10 (4) esu in the tail of absorption.
