Phys. Rev. Lett. 61, 2929–2932 (1988)Nonlinear Focusing of Coupled WavesReceived 29 July 1988; published in the issue dated 26 December 1988 The collinear propagation of an arbitrary number of finite-amplitude waves is modeled by a system of coupled nonlinear Schrödinger equations. This model incorporates the effects of a coordinate-dependent external potential and coordinate-independent nonlinearities. A virial theorem is derived, which governs the nonlinear focusing of these coupled waves. For two light waves in a beat-wave accelerator, the coupling to each other and to the resonantly generated Langmuir wave has a significant effect on the focusing properties of the waves. © 1988 The American Physical Society URL:
