摘　　要：　通过对N31型磷酸盐激光钕玻璃的6种钕离子浓度进行实验,采用Judd Ofelt模型对样品进行分析,发现随着钕离子浓度的增加,受激发射截面逐渐减小。因此在激光系统设计中,应充分考虑钕离子浓度的影响。选择浓度合适的钕玻璃作为工作物质,可使激光系统性能达到最优。Six types of Nd3+ laser glasses of N31 phosphate laser glasses were experimented and analyzed by Judd-Ofelt model. The experimental result shows that when the Nd3+ concentrations increases, the stimulated-emission cross section of the Nd3+ laser glasses decreases, therefore, the influence of Nd3+ should be considered in laser system design.
