近红外1.8-3μm激光玻璃光纤的研究
基本信息
结项摘要
本项目研究了Tm(3+),Ho(3+),Tm(3+)-Ho(3+)等多种单掺和双掺氟化物玻璃在的发光特性与玻璃组成，掺杂浓度和光泵波长的关系，及掺杂离子间的能量转移过程；结果表明，当用800nm光激发双掺玻璃时，通过Tm(3+)离子间的交叉弛豫过程，可把能量从Tm(3+)的(3)H4转移到Ho(3+)的（5）I7能级上，实现Ho(3+)的2.04和2.9μm的敏化发光。拉制出了双包皮结构的参Tm(3+)-Ho(3+)的氟锆酸盐玻璃光纤，用800nm的LD对光纤进行泵浦，发现了荧光光谱随光纤芯径变化的新现象。对Yb(3+)-Tm(3+)上转换发光可用970nm单一波长激发.克服了国外Tm玻璃光纤激光需用双波长或特殊波长泵浦的弊端.这结果为继续研制LD泵浦的2μm和蓝光波段的光纤激光器打下了基础
