The research focus of Sebastian-Paul Kopp is laser-based 3D printing from polymer powders. As described earlier, he uses a technique similar to a common laser printer to individually deposit the powder onto the laser bed. In his subsequent work, he successfully adapted his setup to 3D-print custo...

Last week, the SAOT Summer Academy 2023 was held at the Fraunhofer Research Campus Waischenfeld. Our doctoral candidates learned about current and future display technologies and enjoyed outdoor activities.

At the SAOT Innovation Day 2023, several SAOT investigators – some of them who have just recently joined the network – presented their research to colleagues and doctoral candidates of SAOT: Birgit Stiller: Light-sound interactions for quantum technologies and optical signal processing Hanie...

Leaving the pandemic behind, PhD students from Friedrich-Alexander-Universität Erlangen-Nürnberg (FAU) and Princeton University met again to jointly learn about lasers and photonics. Erlangen, June 2023 – There’s nothing like personal exchange, especially in high complex fields like laser technolog...

In several recent publications, Lisa Ackermann reported her progress on laser beam shaping using spatial light modulators (SLMs). Now she adds another interesting piece of work as she was able to change the color of the shaped light in situ. In her publication “Polarization‑controlled nonlinear comp...

Not all metal is the same. Copper is known to be an excellent heat conductor, but on the other side a very soft and ductile material. Its strength and hardness is far away from the one of steel, which is an alloy of iron and carbon. However, the thermal conductivity of steel is more than an order of...

On May 24, 2023, SAOT members and MAOT students visited the ASML headquarter Veldhoven and gained insights into the company, which is the world's largest supplier of lithography systems for the semiconductor industry.

Last year, Sebastian-Paul Kopp introduced a new technique for powder deposition in laser-based additive manufacturing of polymer structures. He transferred charged polymer particles to the build platform using a locally charged photoconductive plate. This enables high powder efficiency and the print...

Last year, Markus Labus and Peter Lang published on their new setup for optical temperature measurements in flames and aerosols. They continued their efforts and now were able to demonstrate calibration-free imaging of temperature fields in flames containing indium particles. The fluorescent ligh...

Last year, Lisa Ackermann already published on beam shaping of high-energy lasers for materials processing by using spatial light modulators (SLMs). As she pointed out, a drawback is the presence of speckle noise, which overlays the shaped intensity structure and drastically reduces the beam quality...
