影响激光光纤产品质量的因素主要包括稀土离子掺杂浓度、掺杂均匀性、数值孔径、背景损耗和基质材料等,制备方法是利用传统MCVD技术结合稀土离子掺杂工艺来完成特种石英光纤预制棒的制作,完成外形加工后拉制成合格的光纤产品。由于工艺过程复杂,技术环节众多,光纤预制棒制备技术和特种光纤拉制技术均
Factors affecting the quality of laser fiber products include rare earth ion doping concentration, doping uniformity, numerical aperture, background loss and matrix material, the preparation method is the use of conventional MCVD technology combined with rare earth ion doping process to complete special silica optical fiber preform Of the production, after the completion of shape processing drawn into qualified optical fiber products. Due to the complicated process and many technical links, both the optical fiber preform preparation technology and the special optical fiber drawing technology
