In this article, we present LaserCAD, an open-source, script-based software toolkit for the design and visualization of optical setups based on parametric ray tracing. Unlike conventional commercial tools, which focus on complex lens optimization and offer dense GUIs with extensive parameters, LaserCAD…
Plasma wakefield accelerators can be driven either by intense laser pulses (LWFA) or by intense particle beams (PWFA). A third approach that combines the complementary advantages of both types of plasma wakefield accelerator has been established with increasing success over the last decade and is called…
High-power laser sources have essential applications in the fields of industry and research. However, the spectral gain of the active medium often limits the output power of highly demanded laser sources at uncommon wavelengths. Driven by higher requirements of industry and science, laser sources with…
In this thesis, the magnetized, relativistic plasma that overlaps the pump laser in Laser Wakefield Acceleration (LWFA) was investigated. The Jeti 40 laser was used to drive the plasma wave and a transverse, few-cycle probe pulse in the visible to near-infrared spectrum was implemented to image the laser-plasma…
Dünne Aluminiumfolien (0.4 − 8µm) wurden mit Laserpulsen bei relativistischen Intensitäten bestrahlt. Heiße Elektronen, welche periodisch im Laserfeld an der Folienvorderseite beschleunigt werden, emittieren kohärente optische Strahlung (COR) an der Folienrückseite. COR wurde orts- und polarisationsaufgelöst…
In this thesis, various novel aspects of laser-driven ion acceleration with contrast-enhanced laser pulses have been characterized. The maximum ion energies' dependence on the pulse energy and the foil thickness was investigated in a campaign at the POLARIS laser using a plasma mirror for contrast enhancement.…
