Konstantin Vodopyanov MIR Group
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 measurements and ultrasensitive gas-phase molecular detection. We also explore THz imaging via up-conversion of THz photons, as well as applications of lasers and frequency combs for bio-medical research.

Our hikes and kayak adventures
Laser-based Mid-infrared Sources and Applications gives a comprehensive overview of the existing methods for generating coherent light in the important yet difficult-to-reach mid-infrared region of the spectrum (2–20 μm) and their applications.
The book describes major approaches for mid-infrared light generation including ion-doped solid-state lasers, fiber lasers, semiconductor lasers, and laser sources based on nonlinear optical frequency conversion, and reviews a range of applications: spectral recognition of molecules and trace gas sensing, biomedical and military applications, high-field physics and attoscience, and others. Every chapter starts with the fundamentals for a given technique that enables self-directed study, while extensive references help conduct deeper research.
Laser-based Mid-infrared Sources and Applications provides up-to-date information on the state-of the art mid-infrared sources, discusses in detail the advancements made over the last two decades such as microresonators and interband cascade lasers, and explores novel approaches that are currently subjects of intense research such as supercontinuum and frequency combs generation. This important book:
• Explains the fundamental principles and major techniques for coherent mid-infrared light generation
• Discusses recent advancements and current cutting-edge research in the field
• Highlights important biomedical, environmental, and military applications
Group meetings are on Fridays, 9:30-11:00, Room 320 CREOL building (or on Zoom).
