Ultrafast Coherent Bandgap Modulation Probed by Parametric Nonlinear Optics
Sebastian Klimmer, Thomas Lettau, Laura Valencia Molina +5
Light-matter interactions in crystals are powerful tools that seamlessly allow both functionalities of sizeable bandgap modulation and non-invasive spectroscopy. While we often ass…
Unveiling the Role of Electron-Phonon Scattering in Dephasing High-Order Harmonics in Solids
Viacheslav Korolev, Thomas Lettau, Vipin Krishna +8
High-order harmonic generation (HHG) in solids is profoundly influenced by the dephasing of the coherent electron-hole motion driven by an external laser field. The exact physical…
Valley Polarization-Electric Dipole Interference and Nonlinear Chiral Selection Rules in Monolayer WSe
Paul Herrmann, Sebastian Klimmer, Till Weickhardt +6
In monolayer transition metal dichalcogenides time-reversal symmetry, combined with space-inversion symmetry, defines the spin-valley degree of freedom. As such, engineering and co…
High-Harmonic Spectroscopy of Coherent Lattice Dynamics in Graphene
Navdeep Rana, M. S. Mrudul, Daniil Kartashov +2
High-harmonic spectroscopy of solids is a powerful tool, which provides access to both electronic structure and ultrafast electronic response of solids, from their band structure a…
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…
Filamentation of Mid-IR pulses in ambient air in the vicinity of molecular resonances
Valentina Shumakova, Skirmantas Alisauskas, Pavel Malevich +8
Properties of filaments ignited by multi-millijoule, 90-fs mid-IR pulses centered at 3.9 μm are examined experimentally by monitoring plasma density and losses as well as spectral…
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…
