March 2021Ursula Keller received an ERC (European Research Council) Proof of Concept Grant for her project DC-THz "Dual-comb laser driven terahertz spectrometer for industrial sensing".
"Optical absorption spectroscopy in the terahertz (THz) region of the electromagnetic spectrum is used in the industrial sensing and testing of materials, foods, and pharmaceuticals. Within the scope of an ongoing BRIDGE grant of the Swiss National Science Foundation (SNSF), Keller’s team, under the leadership of Dr. Christopher Phillips, has advanced dual-comb laser technology by successfully combining dual optical frequency combs with solid-state lasers producing femtosecond pulses.
Compared to existing lasers used for industrial THz spectroscopy, their breakthrough dual-comb laser technology combines higher performance and lower complexity and could prove less costly than current spectrometers. The additional funding through the ERC-PoC grant enhances the BRIDGE funding and supports the development of a prototype industrial THz spectrometer and the identification of opportunities for its commercialization."
