Nonlinear Optics: a look from the interaction time viewpoint and what it portends

Abstract

I present a simple view of nonlinear optcal phenomena as being determined mostly by the length of interaction time between photons and matter. This may explain why in the last decades the progress in developing better nonlinear materials has not been as rapid as wished. A few tentative routes towards possible improvements in the efficiency of nonlinear optical phenomena are suggested.
