研究了新型掺钕磷酸盐激光玻璃在高能量闪光灯抽运条件下的热破坏性质。激光输出实验表明这种为重复频率激光工作设计的钕玻璃，具有与高峰值功率应用类型的钕玻璃基本相近的激光输出能力，高于早期设计的高能量应用类型的钕玻璃。分析了新型重频工作钕玻璃的热膨胀性质，比较了酸蚀和离子交换前后激光输出性质，测定了重复频率高能量抽运下的极限抽运阈值，并讨论了它们对于耐抽运破坏极限的影响。

Abstract

The pumping damage resistance and thermal properties of the new Nd-doped phosphate laser glass are investigated under high energy flash lamp pumping. The laser output results show that the laser output ability of the new Nd glass specially designed for repetition-rate application is similar to that of the high-peak-power application type Nd glass, and higher than that of the early designed high-energy application type Nd glass. The thermal expansion property of the new Nd glasses is analyzed, as well as their laser output properties before and after acid-etching and ion exchanging. Especially, the pumping thresholds of the new Nd glass are measured under high energy and repetition rate conditions. The impact and correlation among the lasing, pumping, surface strengthening, and thermal properties are analyzed and discussed.
