Optical klystron undulator radiation with electromagnetic wave undulator

Abstract

In the present study we proposed optical klystron in an electromagnet wave undulator. We consider the circularly polarized electromagnetic waves are travelling collinearly in opposite direction formed a beat wave. Spectral properties of the beat wave optical klystron are analysed and investigated using Lienard-Wiechert potential. We observed spikes as well as sidebands on the either side of the fundamental frequency.
