STIMULATED RAMAN EMISSION AND ABSORPTION SPECTROSCOPY. INTENSITY AND GAIN MEASUREMENTS OF THE STIMULATED RAMAN EMISSION IN LIQUID O2 AND N2

Abstract

In liquid O2 and N2 the threshold for stimulated Raman emission is found to be much lower than for other nonlinear processes. Thus it is possible to make reliable measurements of the intensity of Raman emission over a large range of incident laser power by using a simple longitudinal geometry. Several distinct regions of emission were investigated, including normal Raman scattering, exponential gain, onset of oscillation and saturation. There is good agreement with theory. (Author)
