Temporal overlapping for HHG seeded EUV-FEL operation by using EOS-based timing-drift controlling system

Free-electron lasers (FELs), which are based on a self-amplified spontaneous emission (SASE) scheme, have attractive characters as the intense light source in short-wavelength region. However, their temporal profile and frequency-domain spectra have shot-to-shot fluctuating spikes originated from the SASE process. One of the promising approaches to these… CONTINUE READING
