Ultrafast pump-probe laser for the European X-ray free-electron laser facility

摘要

We present a versatile and flexible ultrafast optical laser setup, developed for future experiments at the European XFEL. Like the XFEL, the laser operates in burst-mode, emitting milli-Joule class few-cycle pulses at MHz repetition rates. At its core is an optical parametric amplifier optimized for 800nm emission. We present the design, capabilities, scope of operation and installation schedule.
