摘要
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。
The infra red absorption spectrum of Tm 3+ and Ho 3+ ions in the fluoride glass was investigated. With a Ti∶sapphire laser as exciting source, the cross relaxation process of Tm 3+ ions and infra red emission spectra of Tm 3+ sensitized Ho 3+ ions were studied. The results indicate that the cross relaxation process occurs only when the concentration of Tm 3+ ions is high (about 2 wt%). As the content of Ho 3+ ions increases, 2 μm emission intensity increases too. 2 μm emission intensity reaches maximum when the exciting wavelength is 813 nm.
