Volt-per-Ångstrom terahertz fields from X-ray free-electron lasers Open
The electron linear accelerators driving modern X-ray free-electron lasers can emit intense, tunable, quasi-monochromatic terahertz (THz) transients with peak electric fields of V Å −1 and peak magnetic fields in excess of 10 T when a purp…

Photon diagnostics at the FLASH THz beamline Open
The THz beamline at FLASH, DESY, provides both tunable (1–300 THz) narrow-bandwidth (∼10%) and broad-bandwidth intense (up to 150 uJ) THz pulses delivered in 1 MHz bursts and naturally synchronized with free-electron laser X-ray pulses. Co…

Superradiant Undulator Radiation for Selective THz Control Experiments at XFELs Open
The generation of frequency-tunable, narrow-bandwidth and carrier-envelope-phase stable THz pulses with fields in the MV/cm regime that can be appropriately timed to the femtosecond X-ray pulses from free-electron-lasers is of highest scie…

Simultaneous operation of two soft x-ray free-electron lasers driven by one linear accelerator Open
Extreme-ultraviolet to x-ray free-electron lasers (FELs) in operation for scientific applications are up to now single-user facilities. While most FELs generate around 100 photon pulses per second, FLASH at DESY can deliver almost two orde…
