The THz spectrometer is based on two 1-GHz Ti:sapphire femtosecond lasers which are linked with a fixed repetition rate difference in order to perform high-speed asynchronous optical sampling. One laser drives a high-efficiency large-area GaAs based THz emitter, the other laser is used for electro-optic detection of the emitted THz-field. At a scan rate of 9 kHz a time resolution of 230 fs is accomplished. High-resolution spectra from 50 GHz up to 3 THz are obtained and water absorption lines with a width of 11 GHz are observed. The use of femtosecond lasers with 1 GHz repetition rate is essential to obtain rapid scanning and high time-resolution at the same time.</dcterms:abstract> <dc:contributor>Janke, Christof</dc:contributor> <dcterms:bibliographicCitation>First publ. in: Optics Express 14 (2006), 1, pp. 430-437</dcterms:bibliographicCitation> <dc:creator>Dekorsy, Thomas</dc:creator> <dc:language>eng</dc:language> <dc:creator>Bartels, Albrecht</dc:creator> <dc:contributor>Helm, Manfred</dc:contributor> <dcterms:issued>2006</dcterms:issued> <dc:contributor>Bartels, Albrecht</dc:contributor> </rdf:Description> </rdf:RDF>
