Automated UV-Epoxy-Based Micro-Optic Assembly for Kilowatt-Class Laser-Diode Arrays and Modules Open

G.W. Charache, Scott Licari, Tobias Barnowski, Ulrich Bonna, H. Zimer , et al. · 2019

This paper outlines the numerous interdisciplinary activities required to implement two ultraviolet (UV) epoxy-based automated micro-optic assembly tools within a “smart factory” for high-power semiconductor laser manufacturing. After a br…

Novel, compact, and simple ND:YVO4 laser with 12 W of CW optical output power and good beam quality Open

Ulrich Wittrock, F. Heine, U. Hildebrandt, S. Seel, H. Zimer , et al. · 2017

We present first, promising experiments with a novel, compact and simple Nd:YVO₄ slab laser with 12 W of 1.06 μm optical output power and a beam quality factor M² ∼ 2.5. The laser is made of a diffusion-bonded YVO

Thin-film filter wavelength-stabilized, grating combined, high-brightness kW-class direct diode laser Open

M. Haas, Simon Rauch, Simon Nagel, Lukas Irmler, T. Dekorsy , et al. · 2017

We report on kW-class dense wavelength beam combining of a laser diode module consisting of ten broad-area laser diode bars by using a novel multi-laser cavity approach based on a thin-film filter (TFF) as a dispersive optical element. The…
