Abstract

One of the long-term objectives in the development of high gain free electron lasers (FEL) is to reduce the necessary electron beam voltage for a strong FEL interaction at a given frequency. FEL oscillators (FELOs) play the main role to this end. In this paper, the simulation of one dimensional FELO with planar wiggler is done at the applicable Tera-hertz regime. The effect of pre-bunched electron beam on the gain improvement or on the laser length is investigated. To study the evolution of system, a set of self-consistent nonlinear differential equations are solved numerically by the Runge-Kutta method and the averaging of electron beam is done by the Simpson method.
