摘要
报道了一种能够增强液芯光纤中的受激拉曼散射的外部荧光种子植入法。在毛细管套液芯光纤之间充入荧光染料,实现染料介质与拉曼介质的分离,从外部植入染料荧光种子线性地放大液芯光纤中的受激拉曼散射的初始光强,有效无污染地增强了液芯光纤中拉曼介质的受激拉曼散射强度。实验结果表明,外部荧光染料浓度为最佳值约为10-6 mol/L时,可使液芯光纤中拉曼介质的各阶斯托克斯线均有最大增强。
Abstract
This paper reports an external fluorescence seeding technology which can enhance the stimulated Raman scattering (SRS) in liquid-core optical fiber (LCOF). By surrounding a small section of LCOF with a glass capillary and a solution of Rhodamine 6G filled between them, fluorescent dye and Raman medium are seperated. The initial intensity of SRS is linearly amplified by external fluorescence seeding, and then the SRS of LCOF can be enhanced pollution-free and effectively. Experimental results show that the maximum enhancement of Stokes lines is obtained when the concentration of dye solution is optimized at about 10-6 mol/L.
