研究了氟化物玻璃中Ｔｍ３＋和Ｈｏ３＋离子的红外吸收光谱性质。用钛宝石激光器作为激发源，研究了Ｔｍ３＋离子的交叉弛豫过程和Ｔｍ３＋敏化Ｈｏ３＋的２μｍ的红外发射光谱。研究结果表明：只有当Ｔｍ３＋离子浓度较高（～２ｗｔ％）时，才能发生较强的交叉弛豫过程：随Ｈｏ３＋离子浓度的增加，２μｍ的发光强度增大；当激发光波长为８１３ｎｍ时，２μｍ的发光强度最大
The infrared absorption spectra of Tm3 + and Ho3 + ions in fluoride glass were investigated. Using a Ti: sapphire laser as an excitation source, the cross relaxation process of Tm3 + ions and the 2μm infrared emission spectrum of Tm3 + sensitized Ho3 + were studied. The results show that strong cross-relaxation process occurs only when the concentration of Tm3 + ions is high (~ 2wt%): the luminescence intensity of 2μm increases with the increase of Ho3 + ion concentration; when the excitation wavelength is 813nm, 2μm maximum luminous intensity
