CuO,CuCl对P2O5-ZnO-Na2O玻璃性质的影响

包边技术是提高大尺寸激光玻璃饱和增益系数的关键.为获得优质包边玻璃,以CuO和CuCl分别作为Cu2 的引入物质,采用传统的玻璃熔制方法,研究了Cu2 掺杂量和不同引入物质对P2O5-ZnO-Na2O体系玻璃形成区、析晶稳定性、物化性能以及吸收系数的影响.研究结果表明,CuO和CuCl都能增大P2O5-ZnO-Na2O体系的玻璃形成区、提高玻璃样品的析晶稳定性.玻璃样品的吸收系数随Cu2 掺杂浓度的增加而明显增大,当Cu2 掺杂摩尔分数达到6%时,样品在1053 nm处的吸收系数为59.46 cm-1,基本上达到了饱和状态.     

The effects of B/(B+A1) ratio on glass formation regions and properties of phosphate edge-cladding glasses

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 A1) 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.
