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…
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…
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…
Subcycle phase matching effects in short attosecond pulse trains
N. Ouahioune, R. MartÃn-Hernández, D. Hoff +8
Attosecond pulses produced by High-order Harmonic Generation (HHG) in gases driven by intense laser fields have become a cornerstone technique for probing ultrafast electronic moti…
Compact, intense attosecond sources driven by hollow Gaussian beams
Rodrigo MartÃn-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…
