The problem of the small-signal transverse-mode evolution in free electron lasers is discussed within the framework of an analytical treatment. The analysis is based on the formalism of the amplitude approximants and includes the effect of high gain and inhomogeneous broadening contributions. Mode distortion and focusing effects are derived fairly straightforwardly. We comment on the possibility of including the pulse propagation mechanism.
