Protecting the Edge: Ultrafast Laser Modified C-shaped Glass Edges
Daniel Flamm, Myriam Kaiser, Marvin Feil +4
A procedure and optical concept is introduced for ultrashort pulsed laser cleaving of transparent materials with tailored edges in a single pass. The procedure is based on holograp…
Glass tube cutting with aberration-corrected non-diffracting ultrashort laser pulses
Henning Rave, Henning Heiming, Patrick Szumny +3
The separation of complex inner and outer contours of glass articles with curved surfaces using ultrashort pulsed lasers is reported. Single-pass, full-thickness modifications alon…
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…
Beam shaping for ultrafast materials processing
Daniel Flamm, Daniel Günther Grossmann, Michael Jenne +6
The remarkable temporal properties of ultra-short pulsed lasers in combination with novel beam shaping concepts enable the development of completely new material processing strateg…
High-quality Tailored-edge Cleaving Using Aberration-corrected Bessel-like Beams
Michael Jenne, Daniel Flamm, Taofiq Ouaj +7
We report on the usage of ultrashort laser pulses in form of aberration-corrected Bessel-like beams for laser cutting of glass with bevels. Our approach foresees to incline the mat…
Focal field analysis of highly multi-mode fiber beams based on modal decomposition
Hao Pang, Tobias Haecker, Alexandre Bense +2
In this work, a numerical modal decomposition approach is applied to model the optical field of laser light after propagating through a highly multi-mode fiber. The algorithm for t…
Generalized axicon-based generation of nondiffracting beams
Keyou Chen, Michael Jenne, Daniel Günther Grossmann +1
We generalize the well-known method of generating nondiffracting beams based on axicons by allowing phase modulations with azimuthal dependencies. This generalization includes the…
Real-time determination of laser beam quality by modal decomposition
Oliver A. Schmidt, Christian Schulze, Daniel Flamm +4
We present a real-time method to determine the beam propagation ratio M2 of laser beams. The all-optical measurement of modal amplitudes yields M2 parameters conform to the ISO sta…
