Coherent sensing of atmospheric trace gases for environmental monitoring
Alexander Eber successfully defended his doctoral thesis „Coherent sensing of atmospheric trace gases for environmental monitoring“ on March 26th 2025. We could invite Prof. Mark Wenig, LMU Munich, to Graz as second reviewer who is an expert on remote sensing of air pollutants and other atmospheric parameters
Together with Young Academy Co-Member Jillian Petersen, I got the opportunity to present my research at the Austrian Academy of Sciences in Vienna. "Searching for Trace Gases and Species in the Sea and Atmosphere" was the title of the event on the eve of International Women's Day at the OeAW. It was great to discuss how our complex environment is connected and how we try to learn about it across different scientific disciplines.

Adrian’s work on “Ultra-broadband UV/VIS spectroscopy enabled by resonant dispersive wave emission of a frequency comb” got published in Optics Express!

Ultraviolet Dual Comb Spectroscopy
Lukas Fürst successfully defended his doctoral thesis „Ultraviolet Dual Comb Spectroscopy“ on February 13th 2025. We could invite Prof. Sandrine Galtier, Université Claude Bernard Lyon, to Graz as second reviewer.
Arno Mussot from the University of Lille, France, visited us with his postdoctoral fellow Debanuj Chatterjee and some fibers for spectral broadening and pulse compression for the next level of ultra broadband dual comb spectroscopy.
Thanks, Arno and Deb, for your visit! We had lots of fun with you in the lab and in the Wirtshaus!😊
Nobel laureate Ferenc Krausz visited Graz and the IEP in December 2024. We were so proud while giving him a lab tour! This exceptional day peaked in Ferenc’s inspiring evening talk “Sub-atomic motions probe human health”, this year’s BioTechMed Nobel lecture. We counted more than 500 visitors, our grand lecture hall P1 was too small for so many science enthusiasts.
Thank you so much for coming!
The world’s first broadband UV dual comb spectrometer revolutionizes air pollutant analysis. It enables real-time tracking of pollutants and their reactions with the environment. The work got now published in OPTICA.

We successfully tracked the concentration of nitrogen dioxide in the city of Graz. We achieved a temporal resolution of one minute and a detection sensitivity of only 5 ppb.
To our knowledge, this is the first mobile dual comb spectrometer capable of measuring NO2.

Group Excursion to the Austrian Academy of Sciences (ÖAW) in Vienna for this year’s ISTA Lecture:
Anne L’Huillier talked about “Attosecond Pulses For Studying Ultrafast Electron Dynamics”. The most important step towards attosecond pulses is high harmonic generation that has been studied extensively by Anne L’Huillier and that plays also a crucial part in our Project ELFIS, funded by the ERC.
Group Excursion to the Austrian Academy of Sciences (ÖAW) in Vienna: The German Physical Society (DPG) and the Austrian Physical Society (ÖPG) organized this year`s Lise Meitner Lecture with the ÖAW. Donna Strickland shared her insights and experiences with quite different aspects of chirped pulse amplification in her talk on “Generating High-Intensity, Ultrashort Optical Pulses”.
