  • Lasing with multi-pass gain is achieved in a diamond-based X-ray cavity at the European XFEL, opening a path to next-generation X-ray science.

  • Using the European XFEL free-electron laser, researchers demonstrate terawatt-scale, attosecond hard X-ray pulses. Ten pulse trains per second, each containing hundreds of pulses at megahertz repetition rates, are achieved. Such short and intense pulses at high repetition rate enable unprecedented damage-free X-ray measurements with attosecond temporal resolution.

  • A new scheme for multicolour X-ray free-electron lasers at soft X-ray wavelengths is proposed. The scheme significantly improves two-colour pulse generation and makes possible the first demonstration of three-colour pulse generation.

  • Resonant X-ray excitation of the  45Sc nuclear isomeric state was achieved by irradiation of a Sc-metal foil with 12.4-keV photon pulses from a state-of-the-art X-ray free-electron laser, allowing a high-precision determination of the transition energy.

  • Strong lasing effects similar to those in the optical regime can occur at 1.5–2.1 Å wavelengths during high-intensity XFEL-driven Kα1 lasing of copper and manganese.

  • A cascaded hard X-ray self-seeding system is demonstrated at the European X-ray free-electron laser. The setup enables millijoule-level pulses in the photon energy range of 6–14 keV at the rate of ten trains per second, with each train including hundreds of pulses arriving at a megahertz repetition rate.
