We demonstrate optical parametric generation in two-dimensional purely nonlinear lattices. Experiments performed in hexagonally poled LiTaO3 crystals pumped around 800 nm indicate a coherent contribution to the parametric gain arising from multiple resonances of the lattice, resulting in dual-beam signal outputs in the 1–1.7 μm range.
