…nm; shorter wavelength are more likely to excite fluorescence that can easily hide the Raman scattered light, unless the fluorescence is carefully filtered out. For this reason, near-IR light is often used. Laser sources for continuous wave (CW) Raman spectroscopy include laser diodes, diode-pumped…
