Our group develops groundbreaking techniques for producing mid-IR and terahertz coherent radiation and explores their diverse applications. The areas of research embrace generation of ultra-broadband frequency combs in the mid-IR and THz and study of their coherence properties, Fourier-domain mid-IR spectroscopy including dual-comb spectroscopy, ultrasensitive molecular detection, spectroscopic study of dynamic processes (e.g. combustion), and nano-IR spectroscopy. We also explore supercontinuum generation in fibers and waveguides, photonic THz wave generation, THz imaging via up-conversion, as well as applications of lasers and frequency combs for bio-medical research.
