Description
Seeded free-electron lasers (FELs) are advanced, accelerator-based light sources characterized by high coherence and stability. In previous research, we proposed an intelligent optimization framework for studying seeded FELs. Using this framework for exploratory optimization, we identified a novel seeded FEL scheme. This scheme employs an optical layout identical to echo-enabled harmonic generation (EEHG), but by adjusting the parameters of the seed lasers and chicanes, it achieves bunching factors exceeding the theoretical limit of conventional EEHG. In this paper, we systematically study this novel seeded FEL, presenting its underlying principles. Using a representative set of realistic beam parameters, we demonstrate how this novel scheme induces in the electron beam a high harmonic density modulation.
