Optical characteristics of super-radiant harmonic radiation from a FEL and optical klystron. 3D model
Abstract
In free-electron sources of coherent light, bunching of the electrons allows the super-radiant production of coherent harmonic radiation, up to substantially high harmonic numbers. This paper presents a fully three dimensional model formulation for evaluating coherent harmonic radiation from a free-electron laser or optical klystron. The radiated electromagnetic field is expanded in terms of a set of orthonogonal free-space modes. Expansion coefficients can be evaluated once a generalized form of the FEL pendulum equation has been solved numerically. Preliminary numerical computation of the electron bunching are given. The super-radiant radiation is characterized in terms of spectral brightness parameters and the enhancement in this factor for super-radiant emission as compared to conventional harmonic wiggler radiation is estimated.
