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。

Edge-cladding is a key factor in improving saturated small signal gain coefficient of large laser glass. Two kinds of compound, CuO and CuCl, are used as the original materials of Cu2+. The effects of Cu2+ doping content and different original material on glass forming-regions, crystallization stability, physical and chemical properties and absorption coefficient of P2O5-ZnO-Na2O glasses are studied. The results reveal that both CuCl and CuO can enlarge the glass forming-regions and improve the crystallization stability. The absorption coefficient is improved greatly with the content rise of Cu2+, it reaches 59.46 cm-1 at 1053 nm with CuCl mole percent of 6%, and is almost a maximal value.
