The characteristics of stimulated Raman spectra of birefringent fiber of quartz-based high-Paul-bain fiber are systematically studied, and the seven-stokes and first-order anti-Stokes spectra are given.The thresholds of Raman spectra at various levels are tested, Spectral width and Raman gain, the energy transfer mechanism for forming Raman spectra at all levels is analyzed
