Title: Towards coherent X-ray free-electron lasers

Abstract

Increased bandwidth and fluctuations are difficulties on the path towards generating intense fully coherent X-ray free-electron laser output. A recent experiment at FERMI Trieste observed that these problems can be overcome by an approach called echo-enabled harmonic generation.

Panels a–d refer to the first modulator,more » the first chicane, the second modulator and the second chicane, respectively. The power–distance graph (right) shows that the radiation is exponentially amplified as it travels through the radiator. Middle: experiment set-up.
