“…To make a comparison the intensity of the harmonics for d = 0 is plotted in green. Recent studies on similar topics were performed by other authors, for example, in [34][35][36]. The degradation in brightness and gain due to the energy spread was described in [37].…”

“…However, much depends on the input for the routine and here our analysis may appear useful. Recently, undulators with two, [8,34] and even three [35] periodic magnetic fields were proposed to enhance or suppress high harmonics. Most frequently, such FEL calculations are based on the supposition of an ideal undulator, sometimes energy losses in the beam are included.…”

We present an analytical treatment of the undulator radiation (UR), accounting for major sources of the spectral-line broadening, for example, the beam energy spread, the emittance, and a constant magnetic field, additional to the ideal periodic fields. The examples of high harmonic generation in one-and two-frequency undulators are considered with account for homogeneous and inhomogeneous broadening in real devices. Qualitative estimations are given as well as the exact analytical expressions for the UR spectrum, and intensity are obtained and simplified in the case of high-energy electrons. The compensation of the divergency by the constant magnetic field is demonstrated in the analytical form. The application for free-electron lasers (FEL) is demonstrated and compared with the radiation of a FEL on the supposition of an ideal undulator.

“…Recently, exotic undulators with multiple periodic fields of linear or orthogonal polarization were proposed to regulate high harmonics [13,32]. They often presume an ideal undulator or consider just the beam energy spread [33,34].…”

“…Free electron lasers of short wavelength using modest electron beam energy and to increase the efficiency of FELs system design are the prime target achieved through a harmonic undulator [7][8][9][10][11][12][13][14][15]. In this paper we have presented semi-analytical results for the effect of constant magnetic field on the performance of harmonic undulator at higher harmonics.…”
