We examine the spatiotemporal dynamics of the nonlinear three-wave interaction describing the saturation of an unstable wave by coupling to two damped waves. We observe spatiotemporal chaos involving coherent structures that are characterized by temporal and spatial scales determined by the parameters in the problem.
