Laser-driven high-flux source of coherent quasi-monochromatic extreme ultraviolet radiation for coincidence spectroscopy

Julian Späthe, Sebastian Hell, Martin Wünsche +6

We present a source of coherent extreme ultraviolet (XUV) radiation with a flux of 10${}^{13}$ photons per second at 26.5 eV. The source is based on high-harmonic generation (HHG) in…
