Near single-cycle pulse generation using a cascaded all-bulk multi-pass cell compression system
Saga Westerberg, Gaspard Beaufort, Sara Rushe Palacios +5
We experimentally demonstrate the generation of sub-two-cycle optical pulses using a cascaded post-compression scheme based on two bulk multi-pass cells. Starting from 220 fs, 100…
Enhanced dynamic range spatio-spectral metrology of few-cycle laser pulses
Cristian Alexe, Aaron Liberman, Saga Westerberg +13
Accurate spatio-temporal and spatio-spectral metrology is critical to the characterization and use of ultra-short, high-power lasers. The emergence of few cycle pulses, with bandwi…
Compact, intense attosecond sources driven by hollow Gaussian beams
Rodrigo Martín-Hernández, Melvin Redon, Ann-Kathrin Raab +9
High-order harmonic generation (HHG) enables the up-conversion of intense infrared or visible femtosecond laser pulses into extreme-ultraviolet attosecond pulses. However, the high…
Influence of the laser pulse duration in high-order harmonic generation
Saga Westerberg, Melvin Redon, Ann-Kathrin Raab +10
High-order harmonic generation (HHG) in gases has been studied for almost 40 years in many different conditions, varying the laser wavelength, intensity, focusing geometry, target…
Energy scaling in a compact bulk multi-pass cell enabled by Laguerre-Gaussian single-vortex beams
Victor Koltalo, Saga Westerberg, Melvin Redon +5
We report pulse energy scaling enabled by the use of Laguerre-Gaussian single-vortex () beams for spectral broadening in a sub-40 cm long Herriott-type bulk multi-…
Multiscale carrier-envelope phase characterization of 2-μm pulses delivered by a 200-kHz optical parametric amplifier
Katrin Meier, Arvid Klösgen, Kerstin Harland +7
Light fields with a central wavelength of 2 um are very well suited for strong-field-driven charge carrier control: Their photon energy lies far below the band gap of many material…
Highly versatile, two-color setup for high-order harmonic generation using spatial light modulators
Ann-Kathrin Raab, Marvin Schmoll, Emma R. Simpson +7
We present a novel, interferometric, two-color, high-order harmonic generation setup, based on a turn-key Ytterbium-doped femtosecond laser source and its second harmonic. Each int…
Time-resolved photoemission electron microscopy on a ZnO surface using an extreme ultraviolet attosecond pulse pair
Jan Vogelsang, Lukas Wittenbecher, Sara Mikaelsson +6
Electrons photoemitted by extreme ultraviolet attosecond pulses derive spatially from the first few atomic surface layers and energetically from the valence band and highest atomic…
Measurement of Ultrashort Laser Pulses With a Time-Dependent Polarization State Using the D-Scan Technique
Daniel Diaz Rivas, Ann-Kathrin Raab, Chen Guo +4
The dispersion scan (d-scan) technique is extended to measurement of the timedependent polarization state of ultrashort laser pulses. In the simplest implementation for linearly po…
