摘要：

An investigation of strain and temperature characteristics of Yb-doped fibers has been carried out in this article. Results obtained are compared with those reported on Nd-doped fibers, showing that the lifetime variation rate of the single mode Yb-doped fiber with increasing strain is temperature independent, and within experimental error similar to that of Nd, although in each case, the fiber modes, the dopant concentration level, and the rare earth ion itself are different. Their stable behavior may form the basis of a dual element sensor with which to obtain stress and temperature information independently in so-called "smart structures.''
