Abstract: | We report a 100 nm widely tunable double-clad Ytterbium doped fiber laser. The fiber laser has a linear cavity configuration, where the feedback is provided by a Sagnac fiber mirror on one side, and an external bulk grating on the other side. On the bulk grating side, the fiber has a balled curved-core-termination that suppress backreflection by roughly 50 dB, and does not affect the pump coupling efficiency. The tuning range goes from 1055 nm through 1155 nm, with a maximum output power of 360 mW at 1080 nm, and 0.3 nm linewidth. |
