This combined photochemical-poling processing was also used to produce periodic variations in to accomplish quasi-phase-matched second harmonic generation [14]. Sekkat and co-workers [20] have conducted a much more systematic investigation of laser-assisted poling of azobenzene chromophores in a variety of polymer hosts. In particular, they demonstrated that polar order can be achieved at...
