793 nm抽运下的掺Tm3+碲酸盐玻璃的发光特性
Luminescence of Tm3+-Doped Tellurite Glass Pumped at 793 nm
摘要
研究了掺Tm3+碲酸盐玻璃在793 nm钛宝石激光器抽运下的发光特性,结果发现除常规的3H4→3H6的811 nm荧光外,还存在很强的1G4→3H5的785 nm二光子上转换荧光以及较弱的710 nm和677 nm三光子上转换荧光.
Abstract
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.
