研究了碱金属氟化物对掺Yb3+氟磷玻璃的光谱性质和析晶稳定性能的影响。运用倒易法计算了Yb3+的发射截面。结果显示, LiF的引入对吸收和发射截面的提高作用较大并出现最佳引入量极值, 其次为KF。碱金属氟化物的引入可提高二元体系的析晶稳定性能,使玻璃网络结构得到改善; 拉曼光谱显示二元体系中引入YbF3后玻璃网络结构得到增强, 而在引入碱金属氟化物的三元体系中掺杂YbF3后破坏了网络完整性,降低系统析晶稳定性能。

从理论上详细探讨了基质激光玻璃与包边玻璃的折射率匹配与剩余反射率的关系,并从实验上验证了折射率匹配越好,吸收系数与包边玻璃厚度的乘积越大,则剩余反射率越低,从而对激光放大器中寄生振荡的抑制越好,增益也就越高。

The glass-forming region of P2O5-Al2O3-B2O3-ZnO-Na2O-CuCl system with different Al2O3 and B2O3 contents was studied. The dependence of glasses properties on B/(B+Al) ratio was investigated. The absorption coefficient of copper ion in a specific glass was measured. These results are very helpful to the designing of a cladding glass for large size neodymium phosphate glass.
