Stimulated Raman scattering in sulfur hexafluoride

A preliminary experimental investigation was made of the stimulated Raman scattering in liquid SF₆ at room temperature and saturation vapor pressure of 23 kg/cm². Pumping with ruby laser pulses of 50 nsec duration excited the first and second Stokes components of the scattering at thresholds of 18 and 30 MW/cm², respectively. The Mandel'shtam–Brillouin scattering thresholds of SF₆ were found to depend strongly on the temperature because the medium was close to the critical state.
