Rui Yang, Hong-lei Ma and Hai-peng Jin Influencing factors of external fluorescence seeding enhancing stimulated Raman scattering in liquid-core optical fiber Journal of Raman Spectroscopy 44
This paper reports an external fluorescence seeding technology that effectively enhances stimulated Raman scattering (SRS) while keeping Raman medium uncontaminated in liquid core optical fiber. Experimental results show that both the concentration of fluorescent dye and the seeding position have an influence on enhancement of SRS. The maximum enhancement of Stokes lines is obtained when the concentration of dye solution is optimized at ~106 mol/l and seeding position is located at the input end.
