Study Of CW Stimulated Raman Scattering Of Benzene Influenced By Fluorescence Enhan-cement Effect In Liquid-core Optical Fiber

Stimulated Raman scattering(SRS) is extensively studied, due to it can expand the wavelength range of coherent light and enrich the physical mechanism of coherent radiation. Because scattering light are cumulated by liquid-core optical fiber(LCOF), it has been used to achieve cw SRS process. The researchers achieve out the fluorescence enhancement SRS, through the fluorescence seeding is added to the work solutoins.The technique of the fluorescence seeding enhancement pulse SRS in the liquid droplet and the technique of LCOF are used together in this study. We know that C₆H₆ solution and the hollow core silica fiber have some infrared absorption bands together, while the Stokes line of m-cresol purple in benzene solution lies into a infrared absorption band, we can obtain the SRS spectra with its Stokes lines. The results demonstrate that the fluorescence seeding lower the threshold of benzene SRS, and change the profile of coherent Stokes light. These results have a good application prospect to the continuous Raman lasers.
