The open question of the absolute neutrino mass scale will be addressed by the Karlsruhe Tritium Neutrino (KATRIN) experiment, currently under construction. This thesis reports major contributions to developing and implementing new laser-spectroscopic precision tools to continuously monitor the isotope content of the windowless gaseous tritium source of KATRIN. The method of choice, Raman spectroscopy, is ideally suited for in-situ monitoring of all six hydrogen isotopologues. In a series of beautiful experiments the author obtained two independent novel calibration methods, first based on a comparison of experimental Raman depolarization ratios with corresponding quantum-chemical calculations, and second on a gas sampling technique. Both methods yield consistent cross-calibration results and, as well as yielding improvements in precision, will be of major importance in reducing systematic effects in long-term neutrino mass measurements. The methods developed in this thesis also have great potential to further broaden the applications of Raman spectroscopy to study extended sources such as in atmospheric physics. .Springer Theses, Recognizing Outstanding Ph.D. Research,2190-5053Elementary particles (Physics)Quantum field theoryAtomic structure  Molecular structure SpectroscopyMicroscopyElementary Particles, Quantum Field Theoryhttps://scigraph.springernature.com/ontologies/product-market-codes/P23029Atomic/Molecular Structure and Spectrahttps://scigraph.springernature.com/ontologies/product-market-codes/P24017Spectroscopy and Microscopyhttps://scigraph.springernature.com/ontologies/product-market-codes/P31090Elementary particles (Physics).Quantum field theory.Atomic structure  .Molecular structure .Spectroscopy.Microscopy.Elementary Particles, Quantum Field Theory.Atomic/Molecular Structure and Spectra.Spectroscopy and Microscopy.535.846Schlösser Magnusauthttp://id.loc.gov/vocabulary/relators/aut791826MiAaPQMiAaPQMiAaPQBOOK9910300396803321Accurate Calibration of Raman Systems1770465UNINA
