Spectroscopic properties of Nd3+-doped phosphate glass for three-level laser were investigated for the first time. A 60 nm blue-shift of the three-level transition fluorescence spectrum was achieved by changing the host material from traditional silica glass to phosphate glass. An 880-nm all-fiber laser with a world-record slope efficiency of 42.8% was demonstrated with 25-cm-long 0.25-wt.% Nd3+-doped phosphate fiber. Our research shows that Nd3+-doped phosphate glass is a high-efficiency material for laser operation below 900 nm.

880 nm 高效掺 Nd3+ 磷酸盐光纤激光器

首次研究了Nd3+掺杂磷酸盐玻璃的三能级激光光谱特性。通过将主体材料从传统的石英玻璃改为磷酸盐玻璃,实现了三级跃迁荧光光谱的 60 nm 蓝移。使用 25 厘米长、0.25 重量% Nd3+ 掺杂的磷酸盐光纤证明了具有 42.8% 世界纪录斜率效率的 880 纳米全光纤激光器。我们的研究表明,掺 Nd3+ 的磷酸盐玻璃是一种用于 900 nm 以下激光操作的高效材料。
