All-optical poling is based on the excitation of nonlinear molecules using dual-frequency beams. The process is optimized at a molecular level when the molecules are resonantly excited. From the point of view of frequency conversion applications, this raises the question of device transparency to the frequency converted output. In order to treat this efficiency transparency tradeoff, we recently developed a simple model accounting for all the observable parameters. The model permits a good prediction of the poling dynamics. Its self-consistency permits the description of all the known all-optical poling schemes. In particular, analysis of the parameters of the model permits the identification of new strategies towards the realization of stable and transparent phase-matched materials for frequency conversion. Some preliminary experimental results are presented in this respect.
