    "abstract": "We introduce a novel class of parametric optical solitons supported\nsimultaneously by two second-order nonlinear cascading processes,\nsecond-harmonic generation and sum-frequency mixing. We obtain, analytically\nand numerically, the solutions for three-wave spatial solitons and show that\nthe presence of an additional cascading mechanism can change dramatically the\nproperties and stability of two-wave quadratic solitary waves.",
