摘要：

利用改进化学气相沉积法(MCVD)的反向沉积工艺, 结合无铝的溶液掺杂技术, 制备了高性能掺磷石英基的铒镱共掺光纤. 反向沉积技术表现出了在纤芯中大量沉积磷这类高温下极易蒸发成分上的优势. 研究表明, 这种光纤中, 铒镱离子能量传递效率极高, 掺磷的石英基质对于促进镱离子对铒离子的能量传递, 抑制镱离子寄生荧光作用明显. 最后, 搭建了双包层铒镱共掺光纤激光器系统, 在光纤长度为4 m时, 获得了3.2 W的最大功率输出, 斜率效率达30%.

Abstract:

Fabrication process of efficient Er³⁺:Yb³⁺ co-doped phosphosilicate fibers by modified chemical vapor deposition (MCVD) was reported. The process is combined with the solution doping technique where the codopant of aluminum is absolutely removed. It shows that the backward deposition process can be adapted to incorporate low viscosity phosphate glass and the reason of the porous layer with a higher phosphorus content which is fabricated in that process was discussed in details. The limiting of the back-transfer of energy from erbium ions to ytterbium ions and the suppressing the onset of Yb-ASE are demonstrated by fluorescence spectrum of the perform of phosphosilicate. It shows the efficient energy transfer in this broad absorption, ytterbium-sensitized erbium fiber. The performances of double-cladding Er³⁺:Yb³⁺ co-doped fiber lasers (EY-DCFLs) are also studied experimentally. The maximum output power is about 3.2 W by using a 4 m fiber, with a slope efficiency of 30%.
