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…
Structured light for ultrafast laser micro- and nanoprocessing
Daniel Flamm, Daniel Günther Grossmann, Marc Sailer +9
The industrial maturity of ultrashort pulsed lasers has triggered the development of a plethora of material processing strategies. Recently, the combination of these remarkable tem…
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…
