The wave-action conservation laws for three-wave interactions are of fundamental importance. These laws, known as Manley-Rowe relations, are usually obtained with great difficulty from nonlinear evolution equations. Here, we derive them directly from a Noether symmetry of the appropriate Lagrangian. As an example, the Lagrangian formulation for stimulated Raman scattering is presented, and local Manley-Rowe relations, valid even for noneikonal wave fields, are derived by the Noether method.
