8 August 1989 Effect Of Intensity Scintillation On The Stimulated Rotational Raman Threshold In Hydrogen

Abstract
Threshold measurements of stimulated rotational Raman scattering in hydrogen have been performed for the case of a linear and circularly polarized pump, with and without atmospheric-like phase distortions. Since the effects of Stokes-anti/Stokes (SAS) coupling disappear with circular polarization, the comparison of threshold measurements with each polarization provides a direct measurement of the effective gain reduction caused by SAS coupling combined with turbulence induced intensity scintillations. The results are in good agreement with Raman code calculations.
