SUMMARY:Laserlab-Europe Talk: Dual Comb Spectroscopy for Electronic Fingerprint Spectroscopy
DESCRIPTION:Speaker: Birgitta Schultze-Bernhardt (Graz University of Technology\, Austria)  \n			\n				\n				\n				\n				\n				Dual Comb Spectroscopy combines high spectral resolution with broad spectral coverage and short measurement times. In the recent years\, this spectroscopic method has proven its capabilities in molecular spectroscopy in different spectral regions ranging from the visible across the infrared spectral region into the THz domain [1-3]. The UV has so far been neglected for fingerprinting although electron transitions are as element specific as rovibrational transitions and the corresponding absorption cross sections can be huge (> 100 Mb). Especially molecular gasses of astrophysical and environmental relevance have strong and congested absorption characteristics in this spectral region (few examples: NO2\, CO\, SO2\, HCHO). Birgitta Schultze-Bernhardt will present their latest efforts on expanding dual comb spectroscopy via non-linear frequency up-conversion into the ultraviolet region. The challenges include UV frequency comb generation with a high photon flux\, efficient UV interferometry and fast UV signal detection [4]. \nBirgitta Schultze-Bernhardt is a university professor at the Institute of Experimental Physics at TU Graz\, Austria. Schultze-Bernhardt`s research focus involves the development of ultraviolet frequency comb generation for high resolution molecular spectroscopy. \nReferences \nB. Bernhardt\, A. Ozawa\, P.
