910nm FIBER LASER AND SUPERFLUORESCENCE OF Nd-DOPED SILICA FIBER
掺Nd石英光纤的910nm光纤激光和超荧光

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.
