Abstract : In this article, the small signal gain and exponential gain of the light field when there are random errors in the magnetic field are deduced based on the free electron laser (FEL) longitudinal mode unified theory of Professor Yu Min. In addition, by combining theory with the parameters of the SG-1 device, the scaling relationship between magnetic field errors in the areas of exponential gain sigma and gain parameter g sub 0 is given. Moreover, the three dimensional WAGFEL program is used to simulate the effects of magnetic field random errors on free electron laser gain and saturation gain. Simulations verify the conclusions of linear theory.
