Abstract
It has been previously shown that equivalent results are obtained in FT-Raman spectroscopy using both pulsed and CW excitation if the following two criteria are met. 1) The pulse repetition rate must be significantly higher than the detector roll-off, and 2) The pulse length must be long enough so that interferometer resolution is not degraded. The results using a mode locked Nd/YAG laser operated with various pulse widths will be shown. The operation with pulsed excitation is necessary if one wishes to do a pump-probe Raman experiment for the detection of excited state Raman spectra. The initial results of such an experiment will be shown.
