Coherent and incoherent superposition of transition matrix elements of the squeezing operator
Sandor Varro
We discuss the general matrix elements of the squeezing operator between number eigenstates of a harmonic oscillator (which may also represent a quantized mode of the electromagnet…
High-flux 100-kHz attosecond pulse source driven by a high average power annular laser beam
Peng Ye, Lénárd Gulyás Oldal, Tamás Csizmadia +9
High-repetition-rate attosecond pulse sources are indispensable tools of time-resolved studies of electron dynamics, such as coincidence spectroscopy and experiments with high dema…
Strong laser fields and their power to generate controllable high-photon-number coherent-state superpositions
Javier Rivera-Dean, Theocharis Lamprou, Emilio Pisanty +5
Recently, intensely driven laser-matter interactions have been used to connect the fields of strong laser field physics with quantum optics by generating non-classical states of li…
Attosecond multi-photon multi-electron dynamics
M. Kretschmar, A. Hadjipittas, B. Major +6
Multi-electron dynamics in atoms and molecules very often occur on sub- to few-femtosecond timescales. The available intensities of extreme-ultraviolet (XUV) attosecond pulses have…
Probing Light-Induced Conical Intersections by Monitoring Multidimensional Polaritonic Surfaces
Csaba Fábri, Gábor J. Halász, Ágnes Vibók
The interaction of a molecule with the quantized electromagnetic field of a nano-cavity gives rise to light-induced conical intersections between polaritonic potential energy surfa…
High photon number entangled states and coherent state superposition from the extreme-ultraviolet to the far infrared
Philipp Stammer, Javier Rivera-Dean, Theocharis Lamprou +4
We present a theoretical demonstration on the generation of entangled coherent states and of coherent state superpositions, with photon numbers and frequencies orders of magnitude…
Detailed study of quantum path interferences in high harmonic generation driven by chirped laser pulses
Tamás Csizmadia, Lénárd Gulyás Oldal, Peng Ye +7
We investigate the electron quantum path interference effects during high harmonic generation in atomic gas medium driven by ultrashort chirped laser pulses. To achieve that, we id…
Femtosecond LIPSS on indium-tin-oxide thin films at IR wavelengths
Balazs Banhegyi, Laszlo Peter, Peter Dombi +1
We investigated laser-induced periodic surface structures (LIPSS) generated on indium-tin-oxide (ITO) thin films with femtosecond laser pulses in the infrared region. Using pulses…
Quantum-Optical Spectrometry in Relativistic Laser-Plasma Interactions Using the High-Harmonic Generation Process: A Proposal
Theocharis Lamprou, Rodrigo Lopez-Martens, Stefan Haessler +8
Quantum-optical spectrometry is a recently developed shot-to-shot photon correlation-based method, namely using a quantum spectrometer (QS), that has been used to reveal the quantu…
Pair production seeded by electrons in noble gases as a method for the laser intensity diagnostics
I. A. Aleksandrov, A. A. Andreev
In this study we explore the possibility of using the process of electron-positron pair creation in strong laser fields as a tool for measuring the intensity of the corresponding l…
All-Optical Experimental Control of High-Harmonic Photon Energy
Lénárd Gulyás Oldal, Peng Ye, Zoltán Filus +10
We generate high-order harmonics in gaseous medium with tunable photon energy using time domain interferometry of double pulses in a non-collinear generation geometry. The method i…
Quantum interference in strong-field ionization by a linearly polarized laser pulse, and its relevance to tunnel exit time and momentum
Szabolcs Hack, Szilárd Majorosi, Mihály G. Benedict +2
We investigate the liberation of an atomic electron by a linearly polarized single-cycle near-infrared laser pulse having a peak intensity that ensures tunneling. Based on phase sp…
High-order phase-dependent asymmetry in the above-threshold ionization plateau
M. Kübel, P. Wustelt, Y. Zhang +17
Above-threshold ionization spectra from cesium are measured as a function of the carrier-envelope phase (CEP) using laser pulses centered at 3.1 m wavelength. The directional as…
Single-shot electron imaging of dopant-induced nanoplasmas
C. Medina, D. Schomas, N. Rendler +19
We present single-shot electron velocity-map images of nanoplasmas generated from doped helium nanodroplets and neon clusters by intense near-infrared and mid-infrared laser pulses…
Energetic sub-2-cycle laser with 220 W average power
Steffen Hädrich, Marco Kienel, Michael Müller +12
Few-cycle lasers are essential for many research areas such as attosecond physics that promises to address fundamental questions in science and technology. Therefore, further advan…
