报告简介:For the development of specialty doped optical fiber, a novel method of combining time-resolved / spectroscopic and DSP techniques for fluorescence lifetime measurement has been proposed. In this presentation, Dr. Luo will firstly introduce the principle and measurement procedures of this novel characterization technique. Then, the applications of this new technique for the lifetime measurement of Bi/Er codoped fibre, the identification of multiple bismuth active centre and the assessment of the performance of Er/Yb co-doped optical fibre will be briefed.
