Abstract : This paper treats the growth of the radiation field in two-dimensions of a free electron laser on an electron beam with finite axial and transverse dimensions in the amplifying configuration. The general, self-consistent, nonlinear analysis includes various efficiency enhancement schemes, diffraction and refraction. In the axially symmetric, low gain, resonant macro particle limit, we obtain an analytical expression for the gain. An illustration at 10.6 micrometers is given. (Author)
