Abstract The generation of intense coherent radiation pulses in the far-infrared and terahertz regimes is of considerable interest to the free-electron laser (FEL) radiation user community. At long wavelengths, the diffraction effect can be quite sev

Undulator tapering based on a prebunched electron beam and a strong seed laser has been demonstrated as a promising method to greatly enhance free-electron laser (FEL) efficiency and suppress sideband instability. Different from the former works that

We put forward a method to optimize the step-tapering amplitude of undulator strength and initial energy detuning of electron beam with the goal of maximizing the saturation power of high-gain FELs, based on the physics of longitudinal electron beam
