      Recent developments in attosecond technology led to table-top x-ray spectroscopy in the soft x-ray range, thus uniting the element- and state-specificity of core-level x-ray absorption spectroscopy with the time resolution ...
    • Importance of intensity-to-phase coupling for water-window high-order-harmonic generation with few-cycle pulses

      We present half-cycle cutoff features in the water window using high-order-harmonic generation (HHG) with two-cycle, carrier-envelope-phase-controlled pulses at 1.85 μm in a high-pressure neon target. A relative ...

    • Spatiotemporal isolation of attosecond soft X-ray pulses in the water window 

      Silva, Francisco; Teichmann, Stephan M.; Cousin, Seth L.; Hemmer, Michael; Biegert, Jens (Nature Publishing group, 2015-03-19)
      Article
      Accés obert
      Attosecond pulses at photon energies that cover the principal absorption edges of the building blocks of materials are a prerequisite for time-resolved probing of the triggering events leading to electronic dynamics such ...
    • Three-wave mixing mediated femtosecond pulse compression in BBO 

      Grün, A.; Austin, Dane R.; Cousin, Seth L.; Biegert, Jens (OSA, 2015-10-15)

      Accés obert
      Nonlinear pulse compression mediated by three-wave mixing is demonstrated for ultrashort Ti:sapphire pulses in a type II phase-matched 𝛽�β-barium borate (BBO) crystal using noncollinear geometry. 170 μJ pulses at 800 nm ...
