Study on luminescent prop erties of Yb3+-dop ed phosphosilicate microsphere

  • 摘要: 本文采用双锥光纤与微球腔耦合系统研究成分为55.93P2O5-3.57Al2O3-15Na2CO3-20SiO2的掺Yb3+磷硅酸盐微球腔的合作上转换发光、下转换激光振荡及其级联拉曼激光振荡等发光特性.本实验采用中心波长为976 nm、线宽为0.15 nm的单纵模半导体激光作为抽运光源，在掺Yb3+磷硅酸盐微球腔中测得中心波长为476.1 nm的蓝色合作上转换荧光，并运用合适的理论模型来解释该合作上转换产生11.9 nm蓝移效应的原因.同时，在1058.26 nm和1060.02-1126.08 nm处分别测得了由于微球腔谐振产生的下转换单纵模及多纵模激光振荡.另外，本文首次在同一微球腔中测得了由Yb3+下转换激光激发产生的多级级联拉曼激光.在抽运功率为8.53 mW时，产生的级联拉曼激光可以达到两级，且波长延伸至1300 nm附近.
    Abstract: Cooperative luminescence, down-conversion laser oscillation and cascaded Raman laser in Yb3+-doped 55.93P2O5-3.57Al2O3-15Na2CO3-20SiO2 phosphosilicate glass are studied in the biconical fiber-microsphere coupling system in this paper. A single-mode semiconducter laser with the center wavelength at 976 nm and line-width 0.15 nm is used as a pump source. The blue-shifted cooperative luminescence centered at 476.1 nm is obtained in the Yb3+-doped phosphosilicate microsphere. And a suitable model may be applied to explain the reason for the 11.9 nm blue-shift in this process. Meanwhile, the single-mode laser (at 1058.26 nm) and multimode laser oscillations (from 1060.02 to 1126.08 nm ) have also been obtained as the result of resonant oscillation in microsphere cavity. In addition, for the first time so far as we know a self-stimulated cascaded Raman laser is observed in the same phosphosilicate microsphere, which is generated by the down-conversion laser of Yb3+. When the pump power is 8.53 mW, a two-order cascade Raman laser is generated, which extends the laser wavelength to near 1300 nm.
