Abstract: We discuss a phenomenological one dimensional, self-consistent, multimode (longitudinal) theory for a free electron laser oscillator. A strong fundamental mode and two weak side-band modes are followed through many passes in the optical cavity as the energy of the electron beam decreases monotonically. The time evolution of the laser power exhibits oscillations produced by the sequential growth to saturation and subsequent decay of longitudinal modes evenly distributed in frequency.
