Raman concatenation addresses these challenges by combining two lasers, a single-grating spectrometer, and a single probe to visualize the complete Raman spectra from 0 to 4000 cm −1.

Macquarie University researchers have demonstrated a technique to dramatically narrow the linewidth of a laser beam by a ...

The Raman spectrum above this light would be transmitted, as would any light with lower wavelengths. The sharp cut off means that light close in wavelength would still be transmitted, reaching the ...

Raman spectra of polypropylene (top) and polyethylene (bottom). Spectra are manually offset for visual clarification. Image Credit: Metrohm Middle East FZC. Experimental Details. Water samples were ...

The technique’s non-destructive nature, the selectivity of Raman bands and insensitivity to water make Raman a practical tool for both qualitative and quantitative analysis of organic and inorganic ...
