中文摘要：

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Cu^2＋的引入物质,采用传统的玻璃熔制方法,研究了Cu^2＋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Cu^2＋掺杂浓度的增加而明显增大,当Cu^2＋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。

英文摘要：

　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 Cu^2＋.The effects of Cu^2＋ 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 Cu^2＋,it reaches 59.46 cm^-1 at 1053 nm with CuCl mole percent of 6%,and is almost a maximal value.
