About The Company
Fraunhofer IGD is the international leading institute for applied research in visual computing. Visual computing is image- and model-based information technology and includes computer graphics and computer vision, as well as virtual and augmented reality. In simple terms, the Fraunhofer researchers in Darmstadt, Rostock, and Kiel are turning information into images and extracting information from images. In cooperation with its partners, technical solutions and market-relevant products are created. Prototypes and integrated solutions are developed in accordance with customized requirements. In doing so, Fraunhofer IGD places users at the forefront, providing them with technical solutions to facilitate computer work and make it more efficient. Owing to its numerous innovations, Fraunhofer IGD raises man-machine interaction to a new level. Man is able to work in a more result-oriented and effective way by means of the computer and visual computing developments.
About the 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, offers the opportunity to write a master's thesis on the topic: In-situ analysis of UKP laser structuring in sapphire.

 

Modern laser processes such as Selective Laser-induced Etching ( (SLE) are used to manufacture high-precision glass components for the semiconductor industry, medical technology, and quantum technology with detailed dimensions of < 1 µm. The strong focusing of ultrashort pulsed laser radiation achieves extremely high light intensities of 10^12 W/cm^2, which trigger nonlinear absorption mechanisms and thus enable the processing of transparent materials. Crystalline materials such as sapphire are particularly attractive for many applications due to their hardness and high thermal conductivity. However, the underlying absorption mechanisms of laser radiation in sapphire are still poorly understood. In a first step, a pump-probe system will be used to investigate the absorption mechanisms, the propagation of shock waves, and the formation of stresses and cracks in the femtosecond range.

 

Be part of change

  • You will acquire comprehensive knowledge of processing transparent materials with UKP laser radiation.
  • You will also plan and carry out experiments on the SLE laser processing system.
  • You will perform time- and location-resolved measurements using the pump-probe system.
  • You will analyze and evaluate the results obtained.
  • You will prepare the results for further use.

 

What you contribute

  • You are studying physics or a similar subject and are interested in current topics.
  • You are motivated and committed when it comes to familiarizing yourself with new challenges.
  • You work independently and conscientiously.
  • You enjoy teamwork and actively contribute to a committed environment.

 

What we offer

👥 Team spirit: Creative, interdisciplinary environment with a motivated team, flat hierarchies, and an informal culture.
🖥 Workplace: Excellent range of machines and equipment, as well as first-class office facilities.
💪 Involvement: Practice-oriented thesis in an innovative applied research environment.
🧘 Work-life balance: Benefit from flexible working hours based on trust.
➕ Advantages: Opportunity to benefit from exciting corporate benefits.
