掺钕磷酸盐玻璃的小信号增益性能
Small Signal Gain Coefficients in Nd3+ Doped Phosphate Glass
摘要
测试了应用于神光Ⅱ系列装置93片N31型钕玻璃的小信号增益系数。结果表明,Nd2O3质量分数为2.2%的钕玻璃平均小信号增益系数为0.0387 cm-1,Nd2O3质量分数为3.0%的钕玻璃平均小信号增益系数为0.0416 cm-1,两种浓度的钕玻璃不同样品间小信号增益系数的起伏范围分别为0.86%和0.76%。根据所测定的增益值,表明N31型钕玻璃的增益起伏符合神光Ⅱ系列装置要求,为实现该装置中每一路增益性能的平衡提供了有力保障,也为今后对更大尺寸钕玻璃增益性质的控制提供了经验。
Abstract
Small signal gain coefficients(SSGC) of 93 pieces N31 Nd3+ doped glasses for Shenguang Ⅱ high power laser system are tested. Results show that the average SSGC of Nd glasses with 2.2% mass fraction of Nd2O3 and 3.0% mass fraction of Nd2O3 are 0.0387 cm-1 and 0.0416 cm-1 respectively. Gain fluctuation range of these two kinds of Nd glasses are 0.86% and 0.76% respectively. This result demonstrates that the gain fluctuation range of N31 Nd glasses meets the requests of Shenguang Ⅱ projects and definitely provides the gain equilibrium for every beam laser in this system. This experiment is a valuable experience for controlling the gain properties of even larger Nd glass in the future.
