Abstract

Both sum- and difference-frequency generation in org. materials were demonstrated and explored under conditions where all 3 waves (w1 and w2 ingoing and w1 +- w2 out-going) were resonant with mol. transitions. The expts. were carried out in centrosym. media in which a small elec. field was used to distinguish the polar sublattices. Unique elec. field dependences of the paramagnetic signals were ...
