Optics and laser components out of the printer

28.11.2018

Complete laser systems out of the 3D printer? What sounds like a long way off is the goal of a new research project of the Gottfried Wilhelm Leibniz Universität Hannover (LUH) together with the Laser Zentrum Hannover e.V. (LZH), the Clausthaler Zentrum für Materialtechnik (CZM) and the Hochschule Hannover - University of Applied Sciences and Arts (HsH). They want to 3D print at least parts of a laser system. Because this manufacturing technology enables completely new approaches for the production of lasers and for the lighting industry.

The scientists of the innovation network GROTESK want to 3D print optics and optomechanical components made of different materials, such as glass, polymers and metals, ideally in one step.

In that way, for example, it is possible to create complex optical geometries or to print holders with integrated cooling channels around conventional components, such as laser crystals.

Rethinking manufacturing

"With Additive Manufacturing we can leave conventional thinking behind. The manufacturing of optics and components can be implemented in a completely different way. We are thus creating new design options for optical transmission paths, housing structures and thermal management ", summarizes Dr. Dietmar Kracht, Scientific-Technical Director of the LZH.

In cooperation with the LUH, CZM and HsH, the LZH will define the requirements for the optical elements, create their design and examine the finished products for their optical, thermal and structural properties.

About GROTESK

The project acronym GROTESK stands for “Generative Fertigung optischer, thermaler und struktureller Komponenten“ (generative manufacturing of optical, thermal and structural components).

The project is being carried out in the innovation network under the leadership of the Gottfried Wilhelm Leibniz Universität, together with the Clausthaler Zentrum für Materialtechnik, the Hochschule Hannover - University of Applied Sciences and Arts and the LZH.

The joint research project has a total volume of about 1.9 million euros and is partly financed by the European Regional Development Fund (ERDF) and the State of Lower Saxony.

Im Focus: Successful second round of experiments with Wendelstein 7-X

The experiments conducted from July until November at the Wendelstein 7-X fusion device at the Max Planck Institute for Plasma Physics (IPP) in Greifswald have achieved higher values for the density and the energy content of the plasma and long discharge times of up to 100 seconds – record results for devices of the stellarator type. Meanwhile, the next round of the step-by-step upgrading of Wendelstein 7-X has begun. It is to equip the device for greater heating power and longer discharges. Wendelstein 7-X, the world’s largest fusion device of the stellarator type, is to investigate the suitability of this configuration for use in a power plant.

During the course of the step-by-step upgrading of Wendelstein 7-X, the plasma vessel was fitted with inner cladding since September of last year.

Im Focus: New process discovered: Mere sunlight can be used to eradicate pollutants in water

Advances in environmental technology: You don’t need complex filters and laser systems to destroy persistent pollutants in water. Chemists at Martin Luther University Halle-Wittenberg (MLU) have developed a new process that works using mere sunlight. The process is so simple that it can even be conducted outdoors under the most basic conditions. The chemists present their research in the journal “Chemistry - a European Journal”.

The chemists at MLU rely on electrons moving freely in water, so-called hydrated electrons, to degrade dissolved pollutants.

Im Focus: Ultracold quantum mix

The experimental investigation of ultracold quantum matter makes it possible to study quantum mechanical phenomena that are otherwise hardly accessible. A team led by the Innsbruck physicist Francesca Ferlaino has now succeeded for the first time in mixing quantum gases of the strongly magnetic elements Erbium and Dysprosium and creating a dipolar quantum mixture.

Only a few years ago it seemed unfeasible to extend the techniques of atom manipulation and deep cooling in the ultracold regime to many-valence-electron...

Im Focus: First diode for magnetic fields

Innsbruck quantum physicists have constructed a diode for magnetic fields and then tested it in the laboratory. The device, developed by the research groups led by the theorist Oriol Romero-Isart and the experimental physicist Gerhard Kirchmair, could open up a number of new applications.

Electric diodes are essential electronic components that conduct electricity in one direction but prevent conduction in the opposite one. They are found at the...

Im Focus: Nonstop Tranport of Cargo in Nanomachines

Max Planck researchers revel the nano-structure of molecular trains and the reason for smooth transport in cellular antennas.

Moving around, sensing the extracellular environment, and signaling to other cells are important for a cell to function properly. Responsible for those tasks...
