Broadband Raman spectroscopy (detection bandwidth >1000  cm  −  1) is a valuable and widely used tool for understanding samples via label-free measurements of their molecular vibrations. Two important Raman spectral regions are the chemically specific “fingerprint” (200 to 1800  cm  −  1) and “lo...
