High efficiency tapered free-electron lasers with a prebunched electron beam from echo-enabled harmonic generation
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 introduce an ideal bunching or a seed laser or a...
