The Fraunhofer Institute for Laser Technology, together with the cooperating Chair for Laser Technology (LLT) at RWTH Aachen University, is Europe's leading center for fundamental and contract research in the field of laser technology. In various thesis projects, we offer the opportunity to explore different topics in laser physics within the development of a vacuum-ultraviolet (VUV) frequency comb through high-harmonic generation in the Laser and Optical Systems department.
High-harmonic generation (HHG) enables the generation of coherent radiation in the VUV spectral range down to soft X-rays using infrared (IR) lasers. This makes HHG an important tool with applications in industry and fundamental research, such as VUV frequency comb spectroscopy.
As part of an international research project, we are constructing a VUV frequency comb and offering various topics for thesis projects:
* Development, construction, and characterization of a laser amplifier
* Investigations into lock instabilities of an enhancement resonator during resonator-enhanced HHG
* Development and investigation of piezo mirrors for the length stabilization of an enhancement resonator
What you will do
* Your responsibilities include researching and documenting the state of the art
* You will plan, build, and conduct experiments
* Finally, you will be responsible for documenting and discussing results
What you bring to the table
* You are studying physics or a comparable degree program
* Interest in lasers, application-oriented research, and physical experiments
* Independent, organized, and structured working style
* Initial experience in the areas of laser and optics, electronics, programming, and computer-based data analysis is beneficial
What you can expect
👥 Team Spirit: Creative, interdisciplinary environment with a motivated team, flat hierarchies, and a "you" culture.
🖥 Workspace: Excellent equipment with machines and devices as well as first-class office supplies.
💪 Co-creation: Practical thesis work in an innovative environment of applied research.
🧘 Work-Life Balance: Benefit from flexible working hours based on trust.
➕ Advantages: Opportunity to benefit from exciting corporate wellness programs.
🚐 Commute: Good transport connections, parking spaces directly in front of the institute, an EV charging station, and a parking garage.
The position is limited until the completion of the thesis.
We value and promote the diversity of skills among our employees and welcome all applications, regardless of age, gender, nationality, ethnic and social background, religion, belief, disability, sexual orientation, and identity. Severely disabled persons will be given preference if equally qualified.
With its focus on future-relevant key technologies and the utilization of results in business and industry, the Fraunhofer Society plays a central role in the innovation process. As a guide and catalyst for innovative developments and scientific excellence, it contributes to shaping our society and our future.
