Embodiment 1
[0014] According to the molecular formula, the ratio of raw materials is carried out, and Yb is grown by pulling method 12x : Bi 12(1-x) SiO 20 Crystal, take x=0.5% in the ratio of raw materials. Firstly, high-purity bismuth oxide, silicon oxide and ytterbium oxide are weighed according to the above ratio, mechanically mixed evenly, sintered in a muffle furnace at 1000-1600°C, loaded into a single crystal growth furnace, vacuumed, and filled with nitrogen to carry out crystal growth. After growing the crystal, it was slowly lowered to room temperature, and the crystal was taken out. It was checked that the concentration of Yb ions was evenly distributed, and the optical properties of the crystal were very good.
Embodiment 2
[0016] According to the molecular formula, the ratio of raw materials is carried out, and the Yb obtained by the crucible descending method is grown. 12x : Bi 12(1-x) SiO 20 Crystal, take x=5% in the ratio of raw materials. Firstly, high-purity bismuth oxide, silicon oxide and ytterbium oxide are weighed according to the above ratio, mechanically mixed evenly, sintered in a muffle furnace at 1000-1600°C, loaded into a single crystal growth furnace, vacuumed, and filled with nitrogen to carry out crystal growth. After growing the crystal, it was slowly lowered to room temperature, and the crystal was taken out. It was checked that the concentration of Yb ions was evenly distributed, and the optical properties of the crystal were very good.
Embodiment 3
[0018] use Yb 12x : Bi 12(1-x) SiO 20 The crystal is processed into Φ20×5mm, the two circular surfaces of the crystal are polished and coated, and the laser system is built by using 940nm LD pump to obtain a solid-state laser with 930-1100nm wide tuned laser output.
