Abstract
Stimulated rotational Raman scattering in H2 and D2 has been extensively investigated with pump sources at a variety of wavelengths. As a result of the relative magnitudes of cross sections for vibrational and rotational Raman scattering in these gases and their polarization dependence, for wavelengths shorter than the near IR, rotational scattering in H2 and D2 can dominate over vibrational scattering only for circularly polarized pump radiation. Since the emitted rotational Stokes radiation is then circularly polarized in the opposite sense, it cannot participate in four-wave mixing with two-pump photons.1 Consequently, high-order rotational Stokes and anti-Stokes components are not readily generated in H2 and D2.
