在手套箱中采用传统的熔融淬冷法制备了Ho 3+掺杂的低羟基（OH-）ZnF 2基氟化物玻璃。该玻璃的组成为ZnF 2-BaF 2-SrF 2-YF 3-HoF 3（ZBSY-H），在2.86 µm处，OH-在ZBSY-H玻璃中的吸收系数仅为0.003 cm−1。在1120 nm激光的激发下，在ZBSY-H玻璃中观察到有效的2.86 µm发射。还计算了ZBSY-H玻璃的发射截面，相应的值为1.719 × 10−21 cm 2。这些结果表明，ZBSY-H玻璃是2.86 μm激光应用的潜在候选者。
Ho3+-doped low-hydroxyl (OH-) ZnF2 based fluoride glasses were prepared by using the conventional melt-quenching method in a glove box. The glasses have a composition of ZnF2-BaF2-SrF2-YF3-HoF3 (ZBSY-H), and the absorption coefficient of OH- in the ZBSY-H glasses was calculated to be only ∼0.003 cm−1 at 2.86 µm. Under the excitation of an 1120 nm laser, efficient 2.86 µm emissions were observed in the ZBSY-H glasses. The emission cross section of the ZBSY-H glasses was also calculated, and the corresponding value was ∼7.19 × 10−21 cm2. These results indicated that the ZBSY-H glasses were potential candidate for 2.86 µm laser applications.
