Christoph Lange

Christoph Lange is a Professor in the Department of Physics at the Technical University of Dortmund, where he conducts research in condensed matter physics with a focus on ultrafast optical and terahertz phenomena. He is based in the Faculty of Physics on the North Campus, with his office located in room CP-03-195.

His research interests include the development of tailored optical and THz pulses, nonlinear interactions in condensed matter systems, and advanced time-domain spectroscopy techniques. His work leverages electron-beam-lithography-fabricated resonators to control electromagnetic fields at subcycle and subwavelength scales.

The research conducted by Prof. Lange's group operates on femtosecond timescales, probing fundamental dynamics of electronic excitations using high-field, tunable-frequency pulses ranging from 0.1 THz to over 100 THz. These studies enable unprecedented resolution in observing light-matter interactions, akin to an oscilloscope for light.
