Description

The use of an elliptical waveguide and a planar wiggler with parabolically tapered pole pieces as the terahertz free electron laser (FEL) amplifier model is proposed. A set of self-consistent differential equations for the FEL amplifier is derived by using nonlinear theory, and the characteristics of this amplifier are numerically analyzed. Our numerical simulations are conducted to the 1000 GHz amplifier with an electron beam energy of 1.74 MeV. The results indicate that the peak power of 180 kW and frequency bandwidth of 13.5 GHz can be obtained.
