Bright Coherent Ultrahigh Harmonics in the keV X-Ray Regime from Mid-Infrared Femtosecond Lasers
Tenio Popmintchev, Ming-Chang Chen, Dimitar Popmintchev +17
High harmonic generation traditionally combines ~100 near-infrared laser photons, to generate bright, phase matched, extreme ultraviolet beams when the emission from many atoms add…
Observation of Chiral State Transfer Without Encircling an Exceptional Point
Hadiseh Nasari, Gisela Lopez-Galmiche, Helena E. Lopez-Aviles +7
The adiabatic theorem, a corollary of the Schrödinger equation, manifests itself in a profoundly different way in non-Hermitian arrangements, resulting in counterintuitive state tr…
Topological Modes in a Laser Cavity through Exceptional State Transfer
A. Schumer, Y. G. N. Liu, J. Leshin +8
Shaping the light emission characteristics of laser systems is of great importance in various areas of science and technology. In a typical lasing arrangement, the spatial profile…
High-Performance Mid-IR to Deep-UV van der Waals Photodetectors Capable of Local Spectroscopy at Room Temperature
Daozhi Shen, HeeBong Yang, Christian Spudat +13
The ability to perform broadband optical spectroscopy with sub-diffraction-limit resolution is highly sought-after for a wide range of critical applications. However, sophisticated…
Temporal light control in complex media through the singular value decomposition of the time-gated transmission matrix
Louisiane Devaud, Bernhard Rauer, Matthias Kühmayer +4
The complex temporal behavior of an ultrashort pulse of light propagating through a multiply scattering medium can be characterized experimentally through a time-gated transmission…
Nonlinear propagation effect in x-ray parametric amplification during high harmonic generation
J. Seres, E. Seres, C. Serrat +6
We report the realization and characterization of parametric amplification in high harmonic generation around 100 eV using He gas in a double gas jet arrangement. The delay of the…
