BA/MA on phase noise and lock instability in a boost resonator for HHG

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, a leading center for contract research and development in the field of laser technology, offers the opportunity to write a thesis in the Lasers and Optical Systems department. High-harmonic generation (HHG) offers the possibility to generate coherent radiation in the vacuum-ultraviolet (VUV) spectral range up to soft X-rays with infrared (IR) lasers. This makes HHG an important tool with applications in basic research and industry. However, many applications are limited by the low HHG efficiency. One way to increase the efficiency of HHG is to use boost resonators that are stabilized to the infrared laser. In order to exploit the full potential of a boost resonator, current limitations due to lock instabilities caused by interaction with the plasma must be understood and circumvented.
