【摘要】 本文测试了应用于神光Ⅱ系列装置九十三片N31型钕玻璃的小信号增益系数,结果表明,Nd2O3浓度为2.2wt%的钕玻璃平均小信号增益系数为0.0387cm-1,Nd2O3浓度为3.0wt%的钕玻璃平均小信号增益系数为0.0416cm-1,两种浓度钕玻璃不同样品间的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升级装置要求,为实现该装置中每一路增益性能的平衡提供了有力的保障,也为今后对更大尺寸钕玻璃增益性质的控制提供了经验。更多还原

【Abstract】 Small signal gain coefficients(SSGC) of 93 pieces N31 Nd 3+-doped glasses for Shenguang high power laser system were tested.Results show that the average SSGC of Nd glasses with 2.2wt% Nd 2 O 3 and 3.0wt% Nd 2 O 3 is 0.0387cm-1 and 0.0416cm-1 respectively.Gain fluctuation range of these two kinds of Nd glasses is 0.86% and 0.76% respectively.This result demonstrates that the gain fluctuation range of N31 type Nd glasses meets the requests of Shenguang 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.更多还原
