Abstract
A novel type of spatial modulational instability induced by the dynami cal interaction of two strongly coupled fundamental and harmonic field s in a second-order nonlinear optical material is demonstrated experim entally. This phenomenon is explained theoretically on the basis of a one-dimensional Floquet theory. At high intensities, the formation of a 1D solitary wave lattice is superseded by the onset of 2D modulation al instabilities.
