论文摘要
为了开发稀土掺杂的硫元素纤维制造来感测,放大和激光应用,已经制造了一种核心/甲壳锗硫化物硫化物硫化物纤维掺杂了Pr $^{3+} $。选择了核心和外壳的组成,以通过在GES $ _2 $ -GA -GA $ _2 $ _2 $ s $ _3 $矩阵中分别添加CDI $ _2 $和CSCL来确保正$δ$ n。这些组合物的选择也从实验参数(包括特征温度和粘度)中证明是合理的。此外,从Bragg Graging hoting photo-commiction的角度研究了飞秒激光器硫化物玻璃家族的永久性照片写入。提出了拉曼光谱法的结构研究,并强调了pr $^{3+} $稀土离子对结构的影响。最后,证明了由3.1 $ $ m和5.5 $μ$ m(通过1.55 $μ$ m的泵送)在3.1 $ $ m和5.5 $ m $ m介于3.1 $ m $ m和5.5 $ m $ m之间制造的踏板纤维的发射。
With the ultimate goal of developing rare-earth doped chalcogenide fiber fabrication for sensing, amplification, and laser applications, a core/clad germanium-gallium sulfide fiber doped with Pr$^{3+}$ has been fabricated. The compositions of the core and the clad were selected to ensure the positive $Δ$n by adding CdI$_2$ and CsCl, respectively, in the GeS$_2$ -Ga$_2$S$_3$ matrix. The choice of these compositions was also justified from experimental parameters, including characteristic temperatures and viscosity. Moreover, the permanent photo writability of the sulfide glass family by a femtosecond laser is investigated from the perspective of Bragg grating photo-inscription. Structural investigations by Raman spectroscopy are presented and the effect of the Pr$^{3+}$ rare-earth ion on the structure is underlined. Finally, the emission of the step-index fiber, made by the rod-in-tube technique between 3.1 $μ$m and 5.5 $μ$m (by pumping at 1.55 $μ$m), is demonstrated.
