| 摘 要： | 报道了在液芯光纤内利用四磺酸基苯基卟啉荧光增强苯的高阶受激拉曼散射实验研究. 实验表明:利用荧光效应显著增强苯的高阶受激拉曼谱线的强度;高阶Stokes谱线的阈值明显降低;随着Stokes谱线阶数的增加,Stokes谱线宽度变窄. 用3.55 mJ小能量激光实现了液芯光纤内生物分子荧光增强受激拉曼散射. 此技术对实现宽带受激辐射、种子激光、生物大分子结构研究和生物分子的非生物利用等领域有广阔的应用前景.关键词：受激拉曼散射荧光液芯光纤

| Abstract: | Stimulated Raman scattering of benzene is studied in liquid-core fiber. Owing to fluorescence and third-order nonlinear 4-sulfphenyl porphyin, the high-order stimulated Raman scattering, such as sixth-order Stokes line of benzene, can be observed at a relatively low input-laser power. The threshold of high Stokes line is lowered with the addition of the 4-sulfphenyl porphyin when the concentration of solution is within 10-6 and 10-9 mol/L. At the same time, the Stokes line width becomes narrow with Stokes line order increasing. These results are expected to be applied to tunable laser, seeding laser, biological molecular structures and biological molecule used in none biological area. |
