Generation and characterisation of isolated attosecond pulses at 100kHz repetition rate
Tobias Witting, Mikhail Osolodkov, Felix Schell +8
The generation of coherent light pulses in the extreme ultraviolet (XUV) spectral region with attosecond pulse durations constitutes the foundation of the field of attosecond scien…
Characterization of laser-induced ionization dynamics in solid dielectrics
Peter Jürgens, Benjamin Liewehr, Björn Kruse +8
The formation of an electron-hole plasma during the interaction of intense femtosecond laser pulses with transparent solids lies at the heart of femtosecond laser processing. Advan…
Phase cycling of extreme ultraviolet pulse sequences generated in rare gases
Andreas Wituschek, Oleg Kornilov, Tobias Witting +4
The development of schemes for coherent nonlinear time-domain spectroscopy in the extreme-ultraviolet regime (XUV) has so far been impeded by experimental difficulties that arise a…
Generation and characterization of few-pulse attosecond pulse trains at 100kHz repetition rate
Mikhail Osolodkov, Federico J. Furch, Felix Schell +6
Many experiments in attosecond science will benefit from attosecond pulses at high repetition rates with sufficient photon flux for pump-probe experiments. We use 7fs, 800nm pulses…
Origin of strong-field induced low-order harmonic generation in amorphous solids
P. Jürgens, B. Liewehr, B. Kruse +8
Kerr-type nonlinearities form the basis for our physical understanding of nonlinear optical phenomena in condensed matter, such as self-focusing, solitary waves, and wave mixing. I…
Single-step fabrication of surface waveguides in fused silica with few-cycle laser pulses
Federico J. Furch, W. Dieter Engel, Tobias Witting +2
Direct laser writing of surface waveguides with ultrashort pulses is a crucial achievement towards all-laser manufacturing of photonic integrated circuits sensitive to their enviro…
