PhD position in ultrafast lasers and optical frequency combs, University of Neuchâtel, Switzerland

Time and Frequency Laboratory, Physics Institute, University of Neuchâtel, Switzerland

Research Group of Prof. Thomas Südmeyer 

Optical frequency combs based on ultrafast lasers have enabled numerous scientific and technological breakthroughs. These include the realization of atomic clocks operating at highest precision and novel spectroscopic tools relevant for environmental science, medicine, manufacturing, and safety. However, despite many impressive scientific demonstrations, real-world systems based on frequency combs still suffer from the complexity and cost of the technology required.

In this PhD project, we will investigate novel approaches for the generation of optical frequency combs from ultrafast lasers. We want to overcome limitations of the current technology and demonstrate first proof-of-principle application studies. We are looking for a highly motivated PhD student who would like to conduct research on these topics and develop new classes of frequency combs that will be very attractive for various spectroscopy applications.
