Abstract

The dynamics of multiple Raman scattering in a long path liquid nitrogen (LN2) cell is analysed by using a long pulse unfocused Nd-YAG laser. This medium in this configuration is the most suitable to evaluate the window and mixing effects in the dynamics of the Raman process. In this experiment the window reflections have been evidenced in the time behaviour and they have a calculable effect to lower the Raman threshold. Moreover, some four wave mixing effects have also been calculated and observed both reducing the threshold for the second Stokes scattering and producing a pump regeneration.
