Tracing spatial confinement in semiconductor quantum dots by high-order harmonic generation
H. N. Gopalakrishna, R. Baruah, C. Hünecke +20
We report here on results of experimental-theoretical investigation of high-order harmonic generation (HHG) in layers of CdSe semiconductor quantum dots of different sizes and a re…
Signatures of multi-band effects in high-harmonic generation in monolayer MoS
Lun Yue, Richard Hollinger, Can B. Uzundal +10
High-harmonic generation (HHG) in solids has been touted as a way to probe ultrafast dynamics and crystal symmetries in condensed matter systems. Here, we investigate the polarizat…
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…
Relativistic interaction of long-wavelength ultrashort laser pulses with nanowires
Z. Samsonova, S. Höfer, V. Kaymak +11
We report on experimental results in a new regime of a relativistic light-matter interaction employing mid-infrared (3.9-micrometer wavelength) high-intensity femtosecond laser pul…
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…
Generation of keV hot near-solid density plasma states at high contrast laser-matter interaction
O. N. Rosmej, Z. Samsonova, S. Höfer +13
We present experimental evidence of ultra-high energy density plasma states with the keV bulk electron temperatures and near-solid electron densities generated during the interacti…
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…
Characterization and Application of Hard X-Ray Betatron Radiation Generated by Relativistic Electrons from a Laser-Wakefield Accelerator
Michael Schnell, Alexander Sävert, Ingo Uschmann +3
The necessity for compact table-top x-ray sources with higher brightness, shorter wavelength and shorter pulse duration has led to the development of complementary sources based on…
