Abstract

Stimulated Raman scattering (SRS) of sulfur-II (S-II) phase was investigated by laser decomposition of liquid carbon disulfide. As a matter of fact, above a threshold of the laser intensity, it is suggested that a strong shock wave is generated in the liquid carbon disulfide, which is decomposed owing to the induced high dynamic pressure and temperature. One bending mode E frequency at 289cm1 and one symmetric stretching mode A1 frequency at 490cm1 of S-II phase were observed. The SRS spectra indicated that S-II structure is formed by laser decomposition, as the strong shock wave generates the stable pressure-temperature range of S-II phase. The dynamic high-pressure and static-electric field generated by laser-induced breakdown results in the softening A1 mode becoming more hardened.
