: A tabletop setup for ultrafast x-ray ultraviolet (XUV) magnetic scattering and molecular spectroscopy has been developed at the Laboratory of Quantum Optics at the University of Nova Gorica. This system provides XUV light in a spectral range allowing the study of M-absorption edges in pure transition metals and their alloys, with a pulse duration of 35 fs and a repetition rate of 5 kHz. The experimental setup is optimized for pump-probe XUV magneto-optics, with element selectivity. In addition, the chamber can operate to acquire harmonic spectra generated by selected molecular gases, enabling the investigation of strong-field photoinduced electron dynamics. This paper presents an overview of the setup, along with the results of demonstration experiments.

Abstract
: A tabletop setup for ultrafast x-ray ultraviolet (XUV) magnetic scattering and molecular spectroscopy has been developed at the Laboratory of Quantum Optics at the University of Nova Gorica. This system provides XUV light in a spectral range allowing the study of M-absorption edges in pure transition metals and their alloys, with a pulse duration of 35 fs and a repetition rate of 5 kHz. The experimental setup is optimized for pump-probe XUV magneto-optics, with element selectivity. In addition, the chamber can operate to acquire harmonic spectra generated by selected molecular gases, enabling the investigation of strong-field photoinduced electron dynamics. This paper presents an overview of the setup, along with the results of demonstration experiments.Pubblicazioni consigliate
