Raman spectroscopy is a non-destructive analytical technique that yields detailed information about the chemical structure, crystallinity, and phase of sample matter. It can also be used to investigate various molecular interactions based on the scattering of incident light. Lasers have proven incredibly valuable as light sources for Raman scattering due to their high intensity and practical monochromaticity. But not all Raman spectroscopy lasers are created equally.
