Abstract

Generation of the first Stokes components of stimulated Raman scattering (SRS) in two-component gas mixtures, including the combination component (resulting from scattering of the first (second) Stokes component in the second (first) gas) is studied by numerical methods. The condition for efficient generation of the combination Stokes component is derived and interpreted. It is shown theoretically and by numerical simulation that the optimal ratio of the pressures for the transient SRS generation of the combination component is inversely proportional to the ratio of the Raman scattering cross sections of the two gases. The results of numerical simulation agree well with experimental data.
