摘要
采用电子探针显微分析(EPMA)技术分析和研究了强激光辐照前后连续熔炼钕玻璃中铂金颗粒的各种形态。强激光辐照后的铂金颗粒夹杂物呈现出3种典型的EPMA形貌,这是铂金颗粒吸收激光能量引起的热应力和蒸气压共同作用的结果,钕玻璃的热力学性质对其形态也有一定影响。对比锆和锡夹杂物的EPMA分布特性可以发现铂、锆、锡被共同包裹的现象。
The electron probe micro-analyzer(EPMA) technology is used to analyze and study various forms of platinum(Pt) particle inclusions in continuous-smelted Nd:glass before and after intense laser irradiation. After intense laser irradiation, platinum particle inclusions exhibit three typical EPMA morphology. Their forms come from the joint result of the thermal stress and vapor pressure caused by platinum particles absorbing laser energy. The thermodynamic properties of Nd:glass also have an effect on the morphology. The phenomenon of Pt-Zr-Sn being co-wrapped is found by comparing the EPMA distribution characteristics of zirconium and stannum impurity inclusions.
