| 摘 要： | 报道了国产掺Yb石英光纤激光器的成功运转。用波长为915nm的钛宝石激光泵浦3．5m长的光纤时，激光中心波长为1．03μm，激光阈值可低至5mW，斜效率可达68％。用860nmn泵浦能得到相似的结果。另外，当光纤短于0．5m时能得到974nm激光振荡。

| Abstract: | The operation of a home-made ytterbium-doped fiber laser is reported. When a 3.5 m ytterbium-doped fiber is pumped with a Ti∶sapphire laser at 915 nm, lasing at a wavelength of 1.03 μm occurs. The laser operates at a threshold as low as 5 mW with a slope efficiency as high as 68%. Similar results can also be obtained when the fiber laser is pumped at 860 nm. In addition, when a Yb-doped fiber shorter than 0.5 m was used, laser action at 974 nm was obtained. |
