　　Abstract:

　　BEC based matter wave interferometers are known as high precision measurement tools for gravity. Extending the free propagation time will lead to increase the

　　sensitivity for fundamental research. One way to achieve this is to perform the

　　experiment in space. This leads to new challenges in terms of mechanical and thermal stability. In case of the laser system ZERODUR-based optical benches are a

　　promising technology to fulfill the required stability.

　　Biography:

　　2005 Diploma in Hamburg University
