Nano-Raman spectroscopy is enabling chemical and structural analysis at increasingly smaller scales, opening new possibilities in materials science, nanotechnology and semiconductor research. This seminar will introduce the principles and technical challenges of nano-Raman spectroscopy, with a focus on instrumentation, optical stability and excitation-source requirements.

 

Particular attention will be given to the role of laser coherence, tunability and spectral stability in high-resolution Raman measurements, including perspectives toward tip-enhanced Raman spectroscopy (TERS). The talk will also present ongoing collaboration work of FabNS with CERN around the integration of CERN-developed single-frequency Raman laser technology into a nano-Raman platform, illustrating how advanced laser architectures can support next-generation spectroscopy applications. FabNS is a CERN Venture Connect startup.
