There and back again: Two Humboldt Fellows at once join FLUTE at KIT

There and back again: Two Humboldt Fellows at once join FLUTE at KIT
Date: August 2015
Feodor Lynen Return Fellows

Recently, Gudrun Niehues  and Stefan Funkner  joined the department of Erik Bründermann at KIT for their research projects in cooperation with their former host Prof. Masahiko Tani, director of the Research Center for Development of Far-Infrared Region at the University of Fukui in Japan.

Both researchers, who have a longstanding expertise in the field of terahertz (THz) spectroscopy, have chosen to pursue their research projects at the new FLUTE accelerator facility led by Robert Ruprecht and Prof. Anke-Susanne Müller. During the several years of their stays in Japan, Gudrun Niehues  worked on the development of spectroscopic systems, which were designed for polarization sensitive measurements in the THz regime [1], while Stefan Funkner  constructed a new experiment for non-linear Raman spectroscopy at THz frequencies with chirped picosecond pulses [2].

For their work at KIT, the Alexander von Humboldt Foundation supports both researchers with a Feodor-Lynen Return Fellowship. The two fellows are also supported by the International Scholars & Welcome Office of KIT and Prof. Dirk Wentzel, spokesperson for the regional group of the German Society of Humboldtians, and by their Humboldtian mentor Erik Bründermann, who strives to promote cooperation in research and education with Japan.

Both fellows will utilize the femtosecond laser system of the FLUTE facility. Gudrun Niehues aims to develop single-shot electro-optical sampling techniques, which enables the investigation of smart materials. Stefan Funkner's goal is to advance non-linear and ultrafast measurement techniques.
