摘要
采用改进化学汽相沉积结合溶液掺杂法制备了掺镱石英光纤预制棒,并研究了不同镱掺杂浓度下的吸收光谱和发光光谱.吸收光谱和发光光谱的强度随着YbCl3溶液浓度的增大而增强.在不产生失透的前提下,得到预制棒芯层能够掺杂的YbCl3溶液最大浓度为0.057mol/L.
Yb3+ doped silica glass preforms are fabricated by MCVD process combined with the solution doping technique.Absorption and emission spectra of preforms with various Yb3+ concentrations are investigated.The intensities of absorption and emission increase with increasing of solution concentrations of YbCl3.The maximum YbCl3 solution concentration can be doped into core layer of preform without compromising vitrification is 0.057 mol/L.
