摘要
研究了掺Tm3 + 碲酸盐玻璃在 793nm钛宝石激光器抽运下的发光特性 ,结果发现除常规的3 H4→3 H6的811nm荧光外 ,还存在很强的1G4→3 H5的 785nm二光子上转换荧光以及较弱的 710nm和 6 77nm三光子上转换荧光。
The luminescence of Tm 3+ doped tellurite glass pumped by 793 nm Ti∶Al 2O 3 laser is studied. It is found that there are both strong 785 nm two photon upconversion fluorescence of 1G 4→ 3H 5 transition and weak three photon upconversion 710 nm, 677 nm, fluorescence. The main fluorescence is at 810 nm, which corresponds to 3H 4→ 3H 6 transition. No fluorescence at 1480 nm ( 3H 4→ 3F 4) and 2300 nm ( 3F 4→ 3H 6) were observed.
