Anamorphic beam shaping for efficient laser homogenization: methods and high power applications
Christoph Tillkorn, Andreas Heimes, Daniel Flamm +5
The homogenization of light is widely applied in various industrial sectors. The uniform high power processing of large areas requires a high degree of homogeneity. Sophisticated b…
Dynamic focus shaping with mixed-aperture coherent beam combining
Maike Prossotowicz, Daniel Flamm, Andreas Heimes +5
A novel concept for dynamic focus shaping based on highly efficient coherent beam combining with microlens arrays (MLA) as combining element is presented. This concept allows to co…
Coherent beam combining with micro-lens arrays
Maike Prossotowicz, Andreas Heimes, Daniel Flamm +5
A novel concept for coherent beam combining is presented based on a simple setup with microlens arrays. These standard components are used in a proof-of-principle experiment for bo…
Phonon spectral density in a GaAs/AlGaAs double quantum dot
Andrea Hofmann, Christian Karlewski, Andreas Heimes +6
We study phonon emission in a GaAs/AlGaAs double quantum dot by monitoring the tunneling of a single electron between the two dots. We prepare the system such that a known amount o…
Electronic Decoherence of Two-Level Systems in a Josephson Junction
Alexander Bilmes, Sebastian Zanker, Andreas Heimes +5
The sensitivity of superconducting qubits allows for spectroscopy and coherence measurements on individual two-level systems present in the disordered tunnel barrier of an $\mathrm…
Lasing and transport in a multi-level double quantum dot system coupled to a microwave oscillator
Christian Karlewski, Andreas Heimes, Gerd Schön
We study a system of two quantum dots, each with several discrete levels, which are coherently coupled to a microwave oscillator. They are attached to electronic leads and coupled…
