A simple method for calculating the FEL energy transfer rate
Abstract
The energy transfer rate of FEL and its relevant gain expression were obtained by using a new method deduced in this paper. The advantage was that the difficulty in the calculation due to the perturbation on the electron motion caused by the radiation field was overcome. So that the calculation became rather simple and the higher order revision could be obtained.
