Abstract
Stimulated Raman Spectroscopy (SRS) has demonstrated remarkably high sensitiviw for high resolution applications. The best compromise for obtaining a high signal to noise ratio in SRS is to use a pulsed pump laser and a CW probe laser. In our apparatus the beam of a single mode dye ring laser is passed through 4 stages of an amplifier system pumped by a frequency doubled Nd-YAG laser. We obtain pulses of more than 1 MW peak power and 12ns duration. The Fourier limited linewidth which is about 2.10-3 cm-1 determines the resolving power of the spectrometer.
