Raman spectroscopy has established itself as an extremely capable method in almost all natural scientific disciplines. The renaissance of Raman spectroscopy was mainly triggered by the progress in laser technology and the development of sensitive detectors. Within this contribution we report about the development and application of innovative linear and non-linear Raman technologies (resonance Raman, SERS, CARS etc.) for bio- and material photonics. The activities within biophotonics deal with the localization, identification and structural analysis of biomolecules, bioparticles (e.g. bacteria, yeast, viruses) as well as biological tissue for biomedical diagnostics as well as for environmental and food analysis. The focus within material photonics lies on the characterization of the Franck-Condon point of photoactive systems (e.g. photo catalysts) by means of resonance Raman spectroscopy. The investigation of the Franck-Condon point of photochemical reactions is of utmost importance since it is the starting point for all subsequent electronic relaxation steps and therefore determines the efficiency of a photoreaction.
