Abstract

We investigate the influence of focusing geometry, input power and hydrogen gas pressure on stimulated Raman scattering in H2. It is shown that a weakly focused beam increases the output power of the Stokes lines for all gas pressures. In comparison, a tightly focused beam increases the output powers of the higher-ordered anti-Stokes lines generated by four wave Raman mixing.
