In this dissertation, I report the first thorough investigation and analysis of the nonlinear mode competition and mode evolution from the small signal regime through deep saturation using a time domain full particle simulation code based on the fundamental FEL equations of motion. It is found that the passive eigenmode theory of multimirror resonator FEL is not fully applicable in the large signal saturated regime. Extreme mode competition at the midpoint-phase offset versus beamsplitter reflectance indicating enhanced single mode operation is also discovered. In addition, matrix analysis including the proper form of the FEL gain saturation and the phase of the complex gain is also performed.
