D. Iracane et al., EFFECT OF THE WIGGLER HARMONICS ON THE FREE-ELECTRON LASER DYNAMICS, Nuclear instruments & methods in physics research. Section A, Accelerators, spectrometers, detectors and associated equipment, 341(1-3), 1994, pp. 220-224
We investigate the effect of the wiggler harmonics on the laser genera
tion. The laser field is expanded as a series of modes close to each h
armonic. We point out i) the critical role of the generalized coupling
constants, and ii) the importance of the phase space analysis.
