摘要：

Several basic parameters of Nd3+ in a SiO2-GeO2 glass fibre have been determined. The stimulated emission cross-section for the 4F3/2 --> 4I11/2 transition has been evaluated experimentally both by a laser technique and spectroscopically. Comparison is made between the two methods and a nonradiative decay process inferred. The efficiency of the 800 nm pump band was determined from measurements of laser slope efficiencies. Branching ratios for the different fluorescent bands have been measured and cavity losses determined.
