Abstract:
为提高Yb~(3+)离子在BaWO_4晶体中的掺入量,采用了双掺K~+离子的方法,增大Yb~(3+)离子的分凝系数,使K~+(x(K~+)=0.01),Yb~(3+)(x(Yb~(3+))=0.02):BaWO_4晶体在977 nm处的吸收系数达到α=0.494 cm~(-1).研究了波长为930 nm的LD激光抽运时相应于Yb~(3+)离子~2F_(5/2)→~2F_(7/2)跃迁的960~1 020 nm的荧光光谱,其在1 005 nm处的发射截面σ_(?)=6.286 pm~2,荧光寿命为0.4 ms.实验表明K~+,Yb~(3+):BaWO_4是一种新型近红外激光晶体。
