Transient stimulated Raman scattering in liquids and evaluation of picosecond pulse duration

Observation of spontaneous and stimulated Raman emission in liquids with various Raman linewidths under short pulses excitation shows the absence of self-trapping and Brillouin stimulated scattering, and the normal behavior of unperturbed stimulated Raman emission. The transient effect in liquids with small linewidths makes possible a determination of the linewidth of the laser light, and the duration and intensity of the pulses.
