NSF NeXUS Facility

At the heart of the National Extreme Ultrafast Science Facility (NeXUS) at Ohio State will be an ultrafast laser that delivers a kilowatt of power.  This project will be the first to translate this recently developed technology in high average power, ultrafast lasers developed under the European Extreme Light Infrastructure (ELI) to the United States.  This laser will be used to produce Extreme Ultraviolet (XUV) and soft X-ray pulses by high harmonic generation.  These ultrafast pulses of XUV light will enable researchers to study how electrons move in molecules and materials at time scales as fast as attoseconds and length scales as small as angstroms.  This facility will supply

  • 1 kW laser: 10 mJ at 100 kHz, pulse duration down to 10 fs
  • Drive attosecond and femtosecond XUV and soft x-ray generation
  • Supply XUV light to the following experimental end stations:
    • X-ray absorption and reflection spectroscopy
    • X-ray magnetic circular dichroism
    • Angle-resolved photoelectron spectroscopy
    • Scanning tunneling microscopy
    • Molecular imaging by laser-induced electron diffraction
