Starting from fluid mechanics-Maxwell coupled equations, a gain formula of free electron laser with an axial magnetic field is obtained by use of Laplace transform. The numerieal calculations and the analyses of the dispersion relation indicate that when the electron cyclotron frequency approaches to i-p(i is the frequency of the incident pump wave and p is the electron plasma frequeney), there is a marked drop in the gain and the position of the peak of gain-pump signal mismatch curve shifts downwards from p. We can use the phenomenon of zero-gain to calculate p.
