The Project: “Fiber-based mid-infrared frequency combs for laser spectroscopy and environmental monitoring” is funded by the Foundation for Polish Science (FNP).
The main goal of the Project is to develop novel types of compact fiber-based optical frequency combs in the mid-infrared spectral range, which will be suitable for field deployment and outside-lab operation. Such sources are on demand of many applications, particularly laser spectroscopy, e.g. fast and sensitive detection of multiple air pollutants (especially greenhouse gases) at a time, as well as precision spectroscopy (high-resolution studies of broadband molecular spectra). The broad spectral coverage of frequency combs allows to overcome the major limitation of existing spectroscopic techniques based on continuous-wave (CW) lasers: it enables measurement of entire molecular bands and simultaneous monitoring of multiple gas species. The mid-IR combs developed in the frame of this project will be tested as sources for comb-based spectroscopic systems, incorporating Fourier-transform spectrometers and continuous-filtering Vernier spectrometers.
The second topic of the project is devoted to the development of a femtosecond fiber laser for applications in two-photon excited fluorescence microscopy. This task is done in collaboration with Prof. Maciej Wojtkowski from the Institute of Physical Chemistry, Polish Academy of Sciences (Warsaw, Poland).
The research team involved in the Project consists of young, skilled and strongly motivated scientists well-prepared to solve scientific and technical problems in the wide range of optoelectronics and photonics.
The project is conducted in close cooperation with recognized partners: Dr. Aleksandra Foltynowicz (Umeå University, Sweden), Dr. Gerard Wysocki (Princeton University, US), and Dr. Piotr Masłowski (Nicolaus Copernicus University in Toruń, Poland), world leading researchers with proven track records in the field of optical frequency combs and laser spectroscopy.
