Power Scaling of Ultrashort Pulses by Spatial and Temporal Coherent Combining
Jena : Thüringer Universitäts- und Landesbibliothek Jena, 131 S. (2017) [10.22032/dbt.33668] = Dissertation, Friedrich-Schiller-Universität Jena, 2017
Ytterbium-doped solid-state lasers are versatile tools for the generation of intense ultrashort pulses, which are the key for many industrial and scientific applications. High pulse-peak powers and high average powers are desired at the same time, e.g. [...]

Investigation of laser-plasma interactions at near-critical densities
Jena, 119 pp. (2017) = Dissertation, Friedrich-Schiller-Universität Jena, 2017
During the high-intensity laser-plasma experiments conducted at the high-power lasersystem JETI40 at IOQ, the two qualitatively different laser side-scattering processes havebeen observed. The side-scattering observed during the first experiment was found tobe non-symmetric in nature with respect to the laser’s propagation direction and it wasestimated to occur from under-dense to quarter critical plasma densities.

Aufbau und Charakterisierung einer Quellespinpolarisierter Elektronen für zukünftigeStoßexperimente mit chiralen Molekülen
Gießen : Justus-Liebig-Universität Gießen, 120 S. (2017) = Dissertation, Justus-Liebig-Universität Gießen , 2017
Diese Arbeit beschreibt ein neu am GSI Helmholtzzentrum für Schwerionenforschung aufgebautes Experiment zur Erzeugung spinpolarisierter Elektronenstrahlen für zukünftige Experimente an Speicherringen sowie für unabhängige Experimente im Labormaßstab. Motiviert durch das Ziel der atom- und molekülphysikalischen Erforschung chiraler Systeme deckte die Bündelung der Expertise hessischer Universitäten im LOEWE Schwerpunkt ELCH den Bedarf einer Quellespinpolarisierter Elektronen im Energiebereich von einigen hundert Elektronenvolt bis zu einigen Kiloelektronenvolt auf.

Signatures of the quantum vacuum in inhomogeneous electromagnetic fields
Jena, 167 pp. (2017) = Dissertation, Friedrich-Schiller-Universität Jena, 2017
Abstract: According to the theory of quantum electrodynamics, zero-point fluctuations of the vacuum manifest themselves through the ubiquitous creation and annihilation of virtual electron-positron pairs. These give rise to classically forbidden nonlinear interactions between strong electromagnetic fields in vacuum, first described by Heisenberg and Euler in 1936. [...]
