Thesis: USP laser radiation in glass: Investigation of the excitation behavior for the SLE process(m/w/x)

City: Aachen Date: Apr 2, 2025 # Thesis: USP laser radiation in glass: Investigation of the excitation behavior for the SLE process 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. We offer you the opportunity to write your thesis on the topic of "USP laser radiation in glass: Investigation of the excitation behavior for the SLE process ”. The Micro- and Nanostructuring Group is primarily concerned with the processing of a wide variety of materials, such as metals and glasses, using so-called ultrashort pulsed (USP) laser radiation, with pulse durations in the femto- to picosecond range. With modern laser processes such as selective laser-induced etching (SLE), high-precision glass components with detailed dimensions of < 1 µm are manufactured for the semiconductor industry, medical technology, the optics industry or quantum technology, for example. A current challenge is the increased demands on the surface quality and shape accuracy of the manufactured components. In order to gain a better understanding of the process, in situ investigations of the spatial and temporal excitation behavior are to be carried out. This can then be linked to the subsequent etching behavior. **What you will do** * You will perform experiments on laser systems by yourself and analyze the effects of laser-material interaction. * In particular, you will investigate the spatio-temporal excitation in the glass volume caused by the laser pulse * You will identify and quantify the influence of the excitation on the modification and the resulting surface properties * As part of your work, you will contribute to a better understanding of the process in order to control the process in a targeted manner and make it more precise **What you bring to the table** * You are studying physics, mechanical engineering, materials science or a comparable degree program * You are interested in basic research with a strong application focus, as well as lasers, the smallest dimensions and the production of 3D components * Understanding existing processes and the will to actively contribute to their improvement makes you stand out * You are willing to further develop your knowledge of Python and other relevant software tools * Some knowledge of laser technology is desirable, but not a requirement. **What you can expect** **👥 Team spirit:** Creative, interdisciplinary environment with a motivated team, flat hierarchies and a “you” culture. **🖥 Workplace:** Excellent machinery and equipment as well as first-class office facilities. **💪 Co-creation:** Practice-oriented final thesis in an innovative applied research environment. **🧘‍♀️ Work-life balance:** Benefit from flexible working hours on a trust basis. **➕ Advantages:** Opportunity to benefit from exciting corporate benefits. **🚐 Travel:** Good transport connections, parking spaces directly in front of the institute, an e-charging station and a parking garage. The position is temporary until completion of the final 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 people are given preference if they are equally qualified. **Job Segment:** Mechanical Engineer, Medical Technology, Materials Science, Behavioral Health, Investigation, Engineering, Healthcare, Science, Legal
