abstract
Raman spectroscopy based on spontaneous scattering cannot compete with nonlinear Raman spectroscopy, when the sample volume is large enough to take advantage of the coherent nature of nonlinear optical interactions. However, when the interaction volume is small, the number of optical photons generated through spontaneous Raman scattering can be larger than the number of photons generated by coherent Raman process. In this work, the signal-to-noise ratio for Raman spectroscopy is carefully evaluated, and, by optically amplifying the weak Raman signal, Raman spectra, free of background noise are achieved. 2010 Copyright SPIE - The International Society for Optical Engineering.
