Abstract
The development of attosecond pulses across different photon energies is an essential precursor to performing pump-probe attosecond experiments in complex systems, where the potential of attosecond science can be further developed. We report the generation and characterization of synchronized extreme ultraviolet (90...eV) and vacuum ultraviolet (20...eV) pulses, generated simultaneously via high-harmonic generation. The vacuum ultraviolet pulses are well suited for pump-probe experiments that exploit the high photo-ionization cross-sections of many molecules in this spectral region as well as the higher photon flux due to the higher conversion efficiency of the high harmonic generation process at these energies. We temporally characterized all pulses using the attosecond streaking technique and the FROG-CRAB retrieval method. We report 576±16...as pulses at 20...eV and 257±21...as pulses at 90...eV. Our demonstration of synchronized attosecond pulses at different photon energies, which are inherently jitter-free due to the common-path geometry implemented, offers unprecedented possibilities for pump-probe studies.
