Abstract
Further enhancement of the intense coherent superradiant and stimulated-superradiant emission from prebunched electron beams is possible, in schemes of prebunched beam radiation devices, and particularly free electron laser (FEL). The enhancement of coherent power and spectral power by use of a waveguide, particularly at the zero-slippage condition, is evaluated. A special scheme of a stimulated-superradiance FEL oscillator is analyzed and is shown to feature ultimate radiative energy conversion efficiency (near 100%).
Highlights
In a companion article, the formulation of superradiant (SR) and stimulated-superradiant (ST-SR)radiative emission processes in prebunched electron-beam coherent radiation sources was derived
Special attention was given to the understanding and comparison between the prebunched beam (PB-free electron laser (FEL)) [2 –14] and the coherent synchrotron radiation (CSR) radiation sources [15]
The main results of the formulation are general expressions for the characteristic optical parameters of radiation emitted by the two different coherent emission processes of SR and ST-SR emission
