Attosecond intra-valence band dynamics and resonant-photoemission delays in W(110)
Time-resolved photoelectron spectroscopy with attosecond precision provides new insights into the photoelectric effect and gives information about the timing of photoemission from different electronic...
PublikationenExtreme-ultraviolet frequency combs for precision metrology and attosecond science
Femtosecond mode-locked lasers producing visible/infrared frequency combs have steadily advanced our understanding of fundamental processes in nature. For example, optical clocks employ frequency-comb...
PublikationenPhase-Matching for Generation of Isolated Attosecond XUV and Soft-X-Ray Pulses with Few-Cycle Drivers
Isolated attosecond pulses (IAPs) produced through laser-driven high-harmonic generation (HHG) hold promise for unprecedented insight into physical, chemical, and biological processes via attosecond x-ray...
PublikationenSuppression of individual peaks in two-colour high harmonic generation
This work investigates the suppression of individual harmonics, simultaneously affecting specific even and odd orders in the high-harmonic spectra generated by strongly tailored, two-colour, multi-cycle...
PublikationenOptimum Sample Thickness for Trace Analyte Detection with Field-Resolved Infrared Spectroscopy
The strong absorption of liquid water in the infrared (IR) molecular fingerprint region constitutes a challenge for applications of vibrational spectroscopy in chemistry, biology, and medicine. While high-power...
PublikationenField-resolved infrared spectroscopy of biological systems
The proper functioning of living systems and physiological phenotypes depends on molecular composition. Yet simultaneous quantitative detection of a wide variety of molecules remains a challenge1–8....
PublikationenMulti-octave spanning, Watt-level ultrafast mid-infrared source
We present a source of brilliant mid-infrared radiation, seamlessly covering the wavelength range between 1.33 and 18 ìm(7500–555 cm−1) with three channels, employing broadband nonlinear conversion...
PublikationenBroadband dispersive Ge/YbF3 mirrors for mid-infrared spectral range
Broadband dispersive mirrors operating in the mid-infrared spectral range of 6.5–11.5 ìm are developed for the first time, to the best of our knowledge. The mirrors comprise Ge and YbF3 layers, which...
PublikationenSecond-harmonic generation and self-phase modulation of few-cycle mid-infrared pulses
Near-single-cycle mid-infrared pulses with a spectrum covering 5.4–11 ìmare efficiently frequency-doubled in different GaSe crystals. The second-harmonic spectrum spans 3–4.3 ìm at a power conversion...
PublikationenOptisch gepumpte Magnetometer
Der Nachweis magnetischer Felder und die daraus bestimmbare Magnetisierung der Materialien im geologischen Untergrund erlaubt Einblicke in die natürlichen oder anthropogenen Inhomogenitäten des Untergrundes....
