High-harmonic generation from metasurfaces empowered by bound states in the continuum
George Zograf, Kirill Koshelev, Anastasia Zalogina +9
The concept of optical bound states in the continuum (BICs) underpins the existence of strongly localized waves embedded into the radiation spectrum that can enhance the electromag…
Nonlinear Ionization Dynamics of Hot Dense Plasma Observed in a Laser-Plasma Amplifier
F. Tuitje, P. Martínez Gil, T. Helk +9
From fusion dynamics in stars, to terrestrial lightning events, to new prospects of energy production or novel light sources, hot dense plasmas are of importance for an array of ph…
Discrete dispersion scan setup for measuring few-cycle laser pulses in the mid-infrared
Nils C. Geib, Richard Hollinger, Elissa Haddad +6
In this work, we demonstrate a discrete dispersion scan scheme using a low number of flat windows to vary the dispersion of laser pulses in discrete steps. Monte Carlo simulations…
Wavelength-scale ptychographic coherent diffractive imaging using a high-order harmonic source
Getnet K. Tadesse, Wilhelm Eschen, Robert Klas +9
Ptychography enables coherent diffractive imaging (CDI) of extended samples by raster scanning across the illuminating XUV/X-ray beam thereby generalizing the unique advantages of…
Soliton explosion driven multi-octave supercontinuum generation by geometry-enforced dispersion design in antiresonant hollow-core fibers
Rudrakant Sollapur, Daniil Kartashov, Michael Zürch +9
Ultrafast supercontinuum generation in gas-filled waveguides is one enabling technology for many intriguing application ranging from attosecond metrology towards biophotonics, with…
Avalanche effect and gain saturation in high harmonic generation
Carles Serrat, David Roca, Josep M. Budesca +7
Optical amplifiers in all ranges of the electromagnetic spectrum exhibit two essential characteristics: i) the input signal during the propagation in the medium is multiplied by th…
