About this role
In cooperation with the Chair of Laser Technology (LLT), the Fraunhofer Institute for Laser Technology (ILT)—Europe’s leading center for contract research and development in the field of laser technology—is offering the opportunity to write a thesis on the topic: »Experimental Investigation of the Scalability of Laser Polishing Towards Large Optics for Fusion Applications«.
In laser polishing of glass, surface smoothing is achieved by remelting the surface at temperatures of up to 2100 °C. This enables contactless polishing with very high area throughput and extremely low surface roughness. Current processing concepts limit laser polishing to lens sizes of < 50 mm. Larger areas can be polished by stitching adjacent processing fields; however, this currently causes defects in the transition regions, which are not acceptable for high‑power optics.
Be part of change
- In this thesis, you will systematically investigate processing strategies for transferring the laser polishing process to large optics (Ø 150 mm)
- To achieve this, you will independently plan experiments and carry them out on the laser system
- You will evaluate the experimental results using the available precision measurement equipment
- And you will document and discuss the results
