Spectrum, temporal structure, and fluctuations in a high-gain free-electron laser starting from noise / R. Bonifacio, L. De Salvo, P. Pierini, N. Piovella, C. Pellegrini. - In: PHYSICAL REVIEW LETTERS. - ISSN 0031-9007. - 73:1(1994), pp. 70-73. [10.1103/PhysRevLett.73.70]
Abstract:
We study the time structure, the frequency composition, and the shot to shot fluctuations of the radiation emitted by a free-electron laser starting from shot noise in the electron beam longitudinal distribution, taking into account slippage and finite bunch length effects. We find a very different behavior when the bunch length, scrlb is much longer thatn the cooperation length, scrlc, or of the order of a few scrlc. The field evolution is dominated by slippage effects in both cases, and shows the presence of superradiant spikes.
