Abstract
One-dimension linear theory for free-electron laser with the slow wave medium is set up in terms of Fourier transform in the paper. The eigen fields for the free-electron laser are found and the derivation of the dispersion equations for interaction of electrons with the fields is made. The approximate and analytic expressions for the growth are given. Based on the eigen fields obtained, the mechanisms for the co-gyrotron synchronization and for the inverse-gyrotron synchronization are expounded.
