This invention discloses a new technology for preparing rear earth ionic doped fiber prefabricated rods with DC-RTA technology in a sol-gel method including preparing sol containing necessary doped ions, coating said sol uniformly on the inner wall of the quartz glass tube and burning it under high temperature to coagulate and vitrify them to a doped layer and repeating the above process to form a fiber prefabricated rod by oxygen and hydrogen flame after the doped layer reaches to a designed thickness and the fiber prefabricated rod can be made to various rare earth ionic doped fibers by an ordinary drawbench technology.

本发明属于光纤制造和光纤激光技术领域，具体公开了一种利用溶胶凝胶方法中的DC-RTA技术制备稀土离子掺杂光纤预制棒的新工艺。该工艺步骤包括预先配制好含有所需掺杂离子的溶胶，将该溶胶均匀涂覆在石英玻璃管的内壁后高温灼烧，使之凝结并玻璃化为一层掺杂层。反复上述涂覆灼烧过程，在掺杂层达到设计厚度后由氢氧焰高温收棒形成光纤预制棒。该方法所得到的光纤预制棒可以通过普通拉丝工艺拉制成各类稀土离子掺杂光纤。
