BA/MA Analysis of tensions during 3D glass processing with the SLE process

The Fraunhofer-Gesellschaft (www.fraunhofer.com) currently operates 76 institutes and research institutions throughout Germany and is the world’s leading applied research organization. Around 30 800 employees work with an annual research budget of 3.0 billion euros.

In cooperation with the Chair of Laser Technology at RWTH LLT, the Fraunhofer Institute for Laser Technology ILT, leading center for contract research and development in the field of laser technology, offers the opportunity to write a thesis in the Surface Technology and Form Ablation department. The Chair of Laser Technology LLT at RWTH Aachen University, together with the cooperating Fraunhofer Institute for Laser Technology ILT, is Europe's leading center for basic and contract research in the field of laser technology.

The structuring of transparent materials group focuses on the processing of various materials, such as metals and glasses, with so-called ultrashort pulsed (USP) laser radiation, which has a pulse duration in the picosecond range. Modern laser processes, such as selective laser-induced etching (SLE), are used to produce high-precision glass components for the semiconductor industry, medical technology, the optics industry or quantum technology with detailed dimensions <1µm. One of the current challenges is the detailed understanding of the stress formation in the material and the avoidance of the resulting cracks.

What you will do

Research into stress formation to avoid cracks and better understand the effects of induced stresses on the overall SLE process
The idea of this work is to investigate the known process windows with regard to the development of stresses with varying process parameters and, based on this, to analyze their effects on the entire SLE process
Depending on the subject area and previous knowledge, the results can also be compared with theoretical simulations

What you bring to the table

You are a student in the field of physics/mechanical engineering/materials science or a comparable course of study
Interest in lasers, the smallest dimensions, the production of 3D components
Previous knowledge in the field of laser technology is advantageous, but not essential

What you can expect

Practice-oriented thesis in an innovative working environment
A creative, diverse, multidisciplinary team with in-depth knowledge
Tasks with responsibility and creative freedom
Close cooperation between science and industry
First-class equipment in the laboratories and offices
Good transport links (bus connections, free parking garage)
Flexible working hours for a better work-study balance

The position is temporary until completion of the thesis.
We value and promote the diversity of our employees' skills and therefore welcome all applications - regardless of age, gender, nationality, ethnic and social origin, religion, ideology, disability, sexual orientation and identity. Severely disabled persons are given preference in the event of equal suitability.

With its focus on developing key technologies that are vital for the future and enabling the commercial utilization of this work by business and industry, Fraunhofer plays a central role in the innovation process. As a pioneer and catalyst for groundbreaking developments and scientific excellence, Fraunhofer helps shape society now and in the future.
