摘　　要：以掺镱双包层光纤为例,通过用MCVD工艺结合溶液掺杂法制备掺稀土离子有源光纤过程中,对疏松层脱水条件和脱水成分的研究,给出了脱水条件对有源光纤本底损耗的影响规律。通过优化脱水条件,降低了光纤的本底损耗。By an example of the Yb3＋-doped double-cladding fiber, MCVD process with solution doping method for developing the rare-earth doped active optical fiber is introduced. By researching the dehydration conditions and composition of porous layer after solution doping process, the rule between dehydration conditions and background loss of active optical fiber is concluded. By optimizing the condition of dehydration, the background loss of the fiber is reduced.
