3μm发光掺稀土离子氟磷酸盐激光玻璃及其制备方法
摘要：
一种3μm发光掺稀土离子氟磷酸盐激光玻璃及其制备方法，该玻璃的摩尔百分比组成范围为：Al(PO3)3：15～20％，MgF2：13～17％，CaF2：5～25％，SrF2：5～25％，BaF2：17～22％，NaF：18～22％，RF3(R为稀土元素Er，Pr，Tm，Ho，Nd)：3～5％。采用铂金坩埚和硅碳棒电炉熔融方法制备。本发明玻璃透明，无析晶，在3μm附近红外透过率高，物理化学性质优良，稳定性参数ΔT≥150℃。在980nm波长的激光二极管泵浦下可以获得很强的3μm荧光，适用于3μm发光的掺稀土离子的特种玻璃及光纤材料的制备及应用。
摘要（英）：

The invention relates to 3 mu m luminous rare earth ion doped fluorophosphates laser glass and a preparation method thereof. The glass comprises the following components by molar percent: 15-20% of Al(PO3)3, 13-17% of MgF2, 5-25% of CaF2, 5-25% of SrF2, 17-22% of BaF2, 18-22% of NaF and 3-5% of RF3 (R can be rare-earth elements such as Er, Pr, Tm, Ho, or Nd). The glass is prepared by using a platinum crucible and a silicon carbide rod electric furnace fusion method. The glass in the invention is transparent, has no crystallization, has high infrared transmissivity at the vicinity of 3 mu m wave band, good physical and chemical properties and stability parameter delta T of more than or equal to 150 DEG C and can obtain strong 3 mu m fluorescence under the pumping of a laser diode with a wavelength of 980 nm, and the method is suitable for preparation and application of 3 mu m luminous rare earth ion doped special glass and optical fiber materials.
