Our group develops groundbreaking techniques for producing mid-IR (MIR) and terahertz (THz) coherent radiation and explores their diverse applications. The areas of research embrace generation of ultra-broadband MIR-THz frequency combs and study of their coherence properties, applying dual-frequency-comb MIR-THz spectroscopy for high-resolution spectroscopy and ultrasensitive molecular detection, spectroscopic study of dynamic processes such as combustion, and nano-IR spectroscopy. We also explore THz imaging via up-conversion of THz photons, as well as applications of lasers and frequency combs for bio-medical research.
