摘　　要：测量了Tm3+掺ZBLAN玻璃的吸收谱,确定了Tm3+离子在ZBLAN玻璃中的部分能级位置．测量了266nm紫外激光激发1I6能级的荧光光谱．利用463nm激光激发1G4能级,发现340-370nm上转换荧光带,峰值波长347和362nm,分别对应于1I6-3F4和1D2-3H6跃迁．并根据Judd-Ofelt理论计算了强度参数Ωλ(λ=2,4,6),给出了Tm3+离子在ZBLAN中的振子强度．The Optical absorption of Tm^3＋ in ZBLAN glass and the fluorescence spectrum of the ti6 pumped by 266nm ultraviolet laser have been measured. Two ultraviolet emission bands, centered at 347nm for ^1Ⅰ6→^3F4 Tm^3＋ transition and 362nm for ^1D2→^3H6 Tm^3＋ transition, have been observed by utilizing 463nm laser to excite ^1G4 energy level. The spectral strength parameters and oscillator strength of Tm^3＋ have been calculated according to Judd-Ofelt theory.
