Stimulated Raman scattering is one of the most important problems in the field of nonlinear fiber optics. The Raman scattering enhancement characteristic of Hf-doped silica fiber and Hf/Al co-doped silica fiber are researched. The Raman spectra of Hf-doped silica fiber and Hf/Al co-doped silica fiber are measured by using 785 nm exciting light, and compared with conventional single-mode fiber (SMF). The experimental results show that Hafnium doping or Hafnium/Aluminum co-doping can enhance the optical fiber Raman scattering intensity, and achieve a good Raman scattering enhancement effect.
