Raman imaging and spectroscopy at its limits: Cryogenic temperatures, short wavenumbers, high magnetic fields, and polarization control

This webinar, hosted by Physics Today, presents cryogenic, high-resolution Raman and photoluminescence imaging in high magnetic fields, while resolving low-wavenumber Raman bands and providing full polarization control.

In a combined effort, WITec, the driving force in Raman imaging, and attocube, technology leader in cryogenic microscopy, developed a platform that brings Raman spectroscopic characterization to the edge of absolute zero. In a series of vivid and compelling measurements, we demonstrate how cryoRaman enables high-resolution Raman imaging at various temperatures (down to 2 K) and high magnetic fields (up to 9 T and vector fields) while resolving Raman bands at extremely low wavenumbers (<10 rel. cm^-1) and providing full polarization control.

We hope this session will inspire new ideas and inform new approaches for bringing Raman-based analysis to the next level. We will conclude the presentation with a tutorial on the opportunities and challenges of cryogenic magneto-optics.
