Investigation of the Nonlinear Optical Response in Polymeric Azoester Systems
Résumé
The second and third-order nonlinear optical properties of novel push-pull azobenzene polymers have been investigated using 30 ps laser pulses at 1064 nm. The study of the chromophores has been done before and after corona poling and by employing different polarizations. Very strong nonlinear response, which was different for every investigated system has been found due to enhanced charge transfer within the molecules.
