| Abstract: | In this paper a direct and minute discussion is given of power conservation for volume gratings, based on the calculation of diffraction efficiency. It is shown that two-wave coupled-wave theory do not rigorously conserve power under the weak-coupling assumption. |

| Keywords: | volume gratings weak-coupling |
