2μm高磷含量氟磷酸盐激光玻璃及其制备方法
摘要：
一种2μm高磷含量的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)3：18～22％，BaF2：45～50％，MgF2：10～15％，LiF：8～13％，LaF3：0～6％，RF3(R为稀土元素Yb，Er，Tm，Ho)：4～10％。使用熔融法制备该氟磷酸盐激光玻璃，得到的玻璃透明，无析晶，物理化学性质优良，稳定性参数ΔT≥100℃。在980nm或者800nm波长的激光二极管泵浦下可以获得很强的2μm荧光，适用于2μm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 a 2[mu]m fluo-phosphate laser glass with a high phosphorous content and a preparation method thereof. The glass has the composition by molar percentages as following: 18 to 22 molar percentages of Al(PO3)3, 45 to 50 molar percentages of BaF2, 10 to 15 molar percentages of MgF2, 8 to 13 molar percentages of LiF, 0 to 6 molar percentages of LaF3, and 4 to 10 molar percentages of RF3, wherein R is rare earth elements, such as, Yb, Er, Tm and Ho. A melting method is used for preparing the fluo-phosphate glass, and the prepared glass has good physical and chemical properties, the stability parameter delta T being more than or equal to 100 DEG C and no crystallization. Strong 2[mu]m fluorescence can be obtained by a laser diode pump with the wave length of 980 nm or 800nm. The invention is suitable for the preparation and the application of the 2[mu]m luminous specific glass and the optical-fiber material which are mixed with rare earth ions.
