摘要
It is demonstrated that the use of pulsed lasers in near-infrared Fourier transform Raman spectroscopy can give a significant increase in signal-to-noise ratios over continuous-wave measurements made using the same average laser power. It is also shown that when a thermal (or other relatively long-lived) background is present, the use of pulsed excitation can greatly reduce its effect and, under certain circumstances, can allow it to be substracted completely.
