Abstract

The invention discloses ytterbium-doped fluorphosphate glass with a large emission section and a preparation method of the ytterbium-doped fluorphosphate glass. The ytterbium-doped fluorphosphate glass comprises the following components: 4-10mol% of BaO, 1-5mol% of Al2O3, 10-20mol% of P2O5, 15-25mol% of ZrF4, 12-15mol% of SrF2, 13-18mol% of BaF2 and 15-20mol% of PbF2; the total molar percentage of the components is 100mol%; and Yb2O3 is doped at 1wt%. 5-10mol% of CaF2, 5-10mol% of TeO2, 5-10mol% of Bi2O3 or 5-10mol% of Nb2O5 are added into the components of the glass. The preparation method comprises the following steps of weighing raw materials according to a formula, mixing fully and uniformly, adding to a graphite crucible, using a high frequency furnace to heat to 900-1000 DEG C quickly, keeping warm for 30min, cooling, taking out the glass, placing the glass in a muffle furnace which is heated to glass transition temperature of the glass, keeping warm for 4h, and annealing to the room temperature at a cooling rate of 10 DEG C / h. The glass has a better grain property, and the stimulated emission section is 1.29pm<2>.

Description

[0001] technical field [0002] The invention relates to fluorophosphate laser glass, in particular to ytterbium-doped fluorophosphate glass with a large emission section and a preparation method thereof. [0003] Background technique [0004] Due to its long fluorescence lifetime, high emission efficiency and strong emission intensity, ytterbium-doped laser glass is considered as a potential host material for fiber lasers. Among ytterbium ion-doped laser glasses, fluorophosphate glasses have shown great application potential due to their excellent properties, including low phonon energy, low nonlinear refractive index, and wide transmission range from ultraviolet to near infrared. , high solubility of ytterbium ions, and good thermal and chemical stability. [0005] For ytterbium-doped laser glasses, the fluorescence lifetime τ f and the stimulated emission cross section σ emi are two very important parameters to measure the performance of glass gain. In general, ytter...
