Cr^3＋，Yb^3＋，Er^3＋共掺磷酸盐铒玻璃转镜调Q激光性质研究

研究了Cr^3＋，Yb^3＋，Er^3＋共掺磷酸盐铒玻璃转镜调Q激光性质．三种Er2O3掺杂浓度的激光实验结果表明，在Er2O3名义掺杂浓度为0．5wt％时，玻璃的综合激光性质最好，重复频率为0．1Hz时，它的激光阈值功率为14．5mJ，最大输出能量为9．6mJ，斜率效率为0．55％．在同种实验条件下，比较了Cr14和Kigre公司生产的QE-7S激光性质参数，实验表明，前者激光阈值功率稍低，而后者的斜率效率和最大输出功率略高．

The laser properties of Q-switched Cr3+, Yb3+, Er3+ : phosphate glasses have been studied in this work. Rotating prism Q-switched laser at 1.53 mu m was obtained at room temperature in this erbium glass pumped by flash lamp. The best laser properties are realized in the glass with 0.5wt% Er2O3 concentration. The properties include 14.5mJ threshold energy, 9.6mJ maximum laser output and 0.55% slope efficiency. The laser properties of Cr14 was compared with QE-7S produced by Kigre under the same experimental condition. It is deduced from experimental results that the former has a higher threshold energy, maximum laser output and slope efficiency.
