Description |
An efficient Ytterbium-doped fiber laser (YDFL) operating at 1028 nm is demonstrated using a fiber Bragg grating (FBG). The Ytterbium-doped fiber (YDF) is drawn from Yb(2)O(3)-doped preform, fabricated through deposition of porous layer of composition SiO(2)-GeO(2) by the MCVD process in conjunction with a solution doping technique. The fabricated YDF has a 0.1 mol % of Yb(2)O(3) in the core, a Ytterbium ion lifetime of 1.1 ms, an absorption of 7.65 dB/m at 976 nm. The fiber laser has the maximum efficiency of 51% with pump power threshold of 19 mW using a FBG in conjunction with a Fresnel reflection to form a linear cavity resonator. The efficiency and threshold are better compared to the similar YDFL configuration using a commercial YDF.
