Photoelectron spectroscopy of laser-dressed atomic helium
Severin Meister, Aaron Bondy, Kirsten Schnorr +10
Photoelectron emission from excited states of laser-dressed atomic helium is analyzed with respect to laser intensity-dependent excitation energy shifts and angular distributions.…
A Coincidence Velocity Map Imaging Spectrometer for Ions and High-Energy Electrons to Study Inner-Shell Photoionization of Gas-Phase Molecules
Utuq Ablikim, Cédric Bomme, Timur Osipov +11
We report on the design and performance of a double-sided coincidence velocity map imaging spectrometer optimized for electron-ion and ion-ion coincidence experiments studying inne…
Reconstruction Methods in THz Single-pixel Imaging
Martin Burger, Lea Föcke, Lukas Nickel +2
The aim of this paper is to discuss some advanced aspects of image reconstruction in single-pixel cameras, focusing in particular on detectors in the THz regime. We discuss the rec…
Terahertz dynamic aperture imaging at stand-off distances using a Compressed Sensing protocol
Sven Augustin, Peter Jung, Sven Frohmann +1
In this text, results of a 0.35 terahertz (THz) dynamic aperture imaging approach are presented. The experiments use an optical modulation approach and a single pixel detector at a…
Breaking Imaging Limits using Dithering Masks in 0.35 Terahertz Single-Pixel Imaging
Sven Augustin, Tom Szollmann, Peter Jung +1
In this contribution, we explore the imaging limits of terahertz single-pixel cameras and present a way to improve the achievable signal-to-noise ratio and spatial resolution using…
Mask Responses for Single-Pixel Terahertz Imaging
Sven Augustin, Sven Frohmann, Peter Jung +1
Terahertz (THz) radiation meaning electromagnetic radiation in the range from 0.1 THz (3 mm) to 10 THz (30 mu) has the unique advantage of easily penetrating many obstructions whil…
Isomer-Dependent Fragmentation Dynamics of Inner-Shell Photoionized Difluoroiodobenzene
Utuq Ablikim, Cédric Bomme, Evgeny Savelyev +14
The fragmentation dynamics of 2,6- and 3,5-difluoroiodobenzene after iodine 4 inner-shell photoionization with soft X-rays are studied using coincident electron and ion momentum…
Nonperturbative Bethe-Heitler pair creation in combined high- and low-frequency laser fields
Sven Augustin, Carsten Müller
The nonperturbative regime of electron-positron pair creation by a relativistic proton beam colliding with a highly intense bichromatic laser field is studied. The laser wave is co…
Nonlinear Bethe-Heitler Pair Creation in an Intense Two-Mode Laser Field
Sven Augustin, Carsten Müller
We investigate electron-positron pair creation in the interaction of a nuclear Coulomb field and a highly intense two-mode laser field. For bichromatic laser fields, we examine the…
Interference Effects in Bethe-Heitler Pair Creation in a Bichromatic Laser Field
Sven Augustin, Carsten Müller
We study the creation of electron-positron pairs in the superposition of a nuclear Coulomb field and a two-color laser field of high intensity. Our focus lies on quantum interferen…
