Ernstorfer, R. 2019-02-01 Time- and angle-resolved photoemission spectroscopy (trARPES) employing a 500 kHz extreme-ultraviolet light source operating at 21.7 eV probe photon energy is reported. Based on a high-power ytterbium laser, optical parametric chirped pulse amplification, and ultraviolet-driven high-harmonic generation, the light source produces an isolated high-harmonic with 110 meV bandwidth and a flux of more than 1011 photons/s on the sample. Combined with a state-of-the-art ARPES chamber, this table-top experiment allows high-repetition rate pump-probe experiments of electron dynamics in occupied and normally unoccupied (excited) states in the entire Brillouin zone and with a temporal system response function below 40 fs application/pdf https://folia.unifr.ch/global/documents/307504 https://folia.unifr.ch/documents/307504/files/mon_tar.pdf eng info:eu-repo/semantics/altIdentifier/doi/10.1063/1.5081938 info:eu-repo/semantics/openAccess License undefined Review of Scientific Instruments. - 2019, vol. 90, no. 2, p. 023104 info:eu-repo/classification/udc/53 Time- and angle-resolved photoemission spectroscopy of solids in the extreme ultraviolet at 500 kHz repetition rate http://purl.org/coar/resource_type/c_6501
