| abstract: | We present a simple model of the startup process in a high gain Free Electron Laser (FEL). The model is used to numerically calculate the power generated within the first gain length of the FEL, which is amplified by the remainder of the undulator. The model takes into account the bandwidth and angular limits imposed by the high-gain process. A brief comparison of the results of this model to an analytic approximation for calculating the start-up power is also given. |
