511. JENA Optics Colloquium – Prof. Dr. Ioachim Pupeza
Since May 2018, the traditional JENA Carl Zeiss Optics Colloquium has been held as the JENA Optics Colloquium at the Abbe Center of Photonics on the Beutenberg Campus in Jena and online.
It is open to all interested parties from research, industry, and education, and serves as a forum for new technologies in the field of photonics.
For the 511th edition of the colloquium, we are pleased to welcome Prof. Dr. Ioachim Pupeza with his lecture:
Infrared field-resolved spectroscopy for biomedical applications
The talk presents recent advances in field-resolved spectroscopy (FRS), a technique that enables the measurement of optical electric fields down to their individual oscillations in the THz-to-PHz range—with exceptional sensitivity and linearity.
It focuses on new approaches to simultaneously enhance sensitivity, dynamic range, and bandwidth in the mid-infrared, the so-called molecular fingerprint region. Using electro-optic sampling with powerful 2‑µm gate pulses from thulium fiber lasers, optical fields can be measured linearly over more than 15 orders of magnitude in intensity.
These developments open up new possibilities for (non-)linear infrared spectroscopy of solids, liquids, and gases—pushing toward the fundamental limits set by the nature of light. The talk concludes with an outlook on biomedical applications, including infrared flow cytometry and breath analysis in intensive care settings.
Prof. Dr. Ioachim Pupeza
Prof. Dr. Ioachim Pupeza is a professor at RPTU Kaiserslautern-Landau and a group leader at the Fraunhofer Institute for Industrial Mathematics (ITWM). Starting in 2025, he will also head a research group at the Leibniz Institute of Photonic Technology (Leibniz-IPHT) in Jena.
He studied electrical engineering and mathematics at the Technical University of Braunschweig and earned his PhD in 2011 at the Max Planck Institute of Quantum Optics (MPQ) and Ludwig Maximilian University of Munich (LMU). After a research stay at the Institute of Photonic Sciences (ICFO) in Barcelona, he led the Field-Resolved Infrared Metrology group at the Laboratory for Attosecond Physics (MPQ/LMU) from 2014 to 2023.
His scientific achievements have been recognized with several awards, including an ERC Consolidator Grant (2023) and the Science Award of the Stifterverband (2012). He is a co-founder of IRScope GmbH and actively contributes to scientific committees and funding organizations.

Historie
The JENA Optics Colloquium originated from a lecture series initiated by the Zeiss Works in Jena in 1971, initially intended for employee training. By attracting high-profile speakers, it quickly evolved into an important discussion platform for leading optics experts in Germany.
After 1989, the colloquium was continued in cooperation with the Institute of Applied Optics at the University of Jena, represented by Prof. Kowarschik. Its significance grew further through the involvement of top scientists, companies, and collaborations with institutes such as the Fraunhofer IOF and the Leibniz IPHT.
