Start-to-end simulation of a Smith-Purcell free electron laser
Terahertz (THz) radiation has generated much recent interest due to its ability to penetrate deep into many organic materials without the damage associated with ionizing radiations. Smith-Purcell free-electron lasers (SPFELs) offer a viable path toward generating copious amounts of narrow-band THz radiation. In this paper we present numerical simulations, performed with the conformal finite-difference time-domain electromagnetic solver VORPAL of a SPFEL operating in the superradiant regime. We first explore the standard (single grating) configuration and investigate the impact of incoming beamparameters. We also present a new concept based a double grating configuration to efficiently bunch the electron beam, followed by a single grating to produce super-radiant SP radiation.
