摘　　要：用函数逼近方法，将单模光纤中的光场分解为若干个高斯光束的迭加。在此基础上讨论了光纤端面相距反射镜为Ｌ时的耦合损耗。解释了实验中观测到的光纤耦合损耗行为。The electric field component of LP01 mode at the end of a monomode fiber is expanded into a superposition of Gauss- Laguerre series in terms of the function approximation method. The butted loss has been calculated when the distance between the fiber end and the mirror is L. The butted loss measured in the experiemts has thus been explained.
