Combs of light for molecules

Nanowerk  March 7, 2019 Researchers in Germany review the developments and prospects in the emerging and quickly advancing field of atomic and molecular broadband spectroscopy with frequency combs. The past decade has witnessed remarkable progress in laser frequency comb generators dedicated to broadband spectroscopy, especially in the molecular-fingerprint mid-infrared (2–20 µm) region and the ultraviolet range (<400 nm). Existing spectrometers and spectrometric techniques have been adapted and improved to make the most of such sources (mode-locked lasers, nonlinear frequency conversion, microresonators, electro-optic modulators, semi-conductor lasers etc.), while entirely new comb-enabled approaches and instruments have been explored…read more.
