Phys. Rev. A 34, 4843–4850 (1986)Even-harmonic generation in free-electron lasersReceived 21 July 1986; published in the issue dated December 1986 A harmonic-generation mechanism that relies on the coupling modulation between an electron orbit and an electromagnetic mode is proposed. Applications of this mechanism to harmonic generation in linearly polarized free-electron lasers predicts the emission of even-harmonic radiation in the forward direction primarily in the TEM01 mode. © 1986 The American Physical Society URL:
