The free electron laser gain formulae for low-, intermediate-, and high-gain domains are parametrized by means of a simple expression reproducing linear and exponential regimes. The proposed reformulation provides a useful tool of analysis because of its remarkable simplicity and because it offers the possibility of deriving comparably simple gain formulae that include inhomogeneous broadening effects. © 1995 American Institute of Physics.
