摘　　要：用514.5nmAr离子激光泵浦掺Nd石英单模光纤,通过抑制1080nm的发射,取得了910nm波段的光纤激光和超荧光输出.光纤激光的最大输出功率为1.4mW,斜率效率为2.5%.光纤超荧光的最大输出为0.4mW.比较了在单程和双程构置情况下910nm和1080nm超荧光输出间的关系.实验还研究了在同一构置中光纤输出从超荧光到振荡激光的变化过程.Pumped by 514.5nm Ar ion laser, 910nm laser and superfluorescence operation of Nd-doped silica fiber were achieved by suppressing the emission at 1080nm. The maximal output of 910nm fiber laser is 1.4mW, slope efficiency is 2.5%. The maximal out- put of 910nm superfluorescence is 0.4mW. An experimental comparison was made be- tween the outputs at 1080nm and 910nm superfluorescence. The process of change of the output from the superfluorescence to oscillatory laser in the same configuration was dem- onstrated by the experiment.
