Forschungsförderungsprojekt
Infrared spectral continuum is of high interest for numerous applications such as precision frequency metrology, femtosecond pulse phase stabilization, ultrashort pulse compression, optical coherence tomography, high-resolution spectroscopy, etc. Until recently production of the infrared supercontinuum beyond 2 µm involved using the rather complex and costly nonlinear conversion schemes. This project aims at the development of the compact and low cost infrared spectral continuum sources with controllable parameters. The latter promises a break-through in the field of the infrared laser technique and nonlinear optics. To achieve this ambitious aim we plan to employ novel infrared microstructured and liquid-cladded tapered fibers, nanocrystalline-doped fibers, and fibers made of strongly nonlinear crystalline materials, as well as semiconductor bulk media. In combination with the novel all-solid-state lasers based on the diode-pumped mode-locked Cr4+:YAG (1.4-1.6 µm) and Cr2+:Zinc-chalcogenide (2-3 µm) oscillators, this will provide an extension of the supercontinuum technique into the important mid-infrared region beyond 2 µm and will open up the new prospects for precision metrology, nonlinear optics and medicine. As a result of the project, compact transportable frequency comb sources spanning the range from atomic frequency standards in the near-infrared to molecular frequency standards in the mid-infrared will become a reality.
