article description
Based on processes involving the cascading of two successive second-order nonlinear interactions, we show how novel, all-optical approaches to signal processing can be exploited by coherent interactions between three waves in noncentrosym-metric materials. Specifically, we emphasize the coherent seeding of the second-harmonic generation process with waves at one of the participating frequencies. Copyright 1995 IEEE
