The effect of La2O3 in Tm3+-doped germanate-tellurite glasses for ~2 μm emission
A germanate-tellurite glass (GeO2-TeO₂-K₂O-Nb₂O₅-La₂O₃) with thulium doping has been investigated for application as a laser material around 2.0 μm regions. Under the 808 nm laser diode pumped, intense 1.8 μm emission is obtained. Based on the absorption spectra, radiative properties are predicted using Judd-Ofelt theory. The maximum value of emission cross-section of Tm(3+) around 1.8 μm can r...
متن کاملPreparation of Ho3+/Tm3+ Co-doped Lanthanum Tungsten Germanium Tellurite Glass Fiber and Its Laser Performance for 2.0 μm
Ho3+/Tm3+ co-doped 50TeO2-25GeO2-3WO3-5La2O3-3Nb2O5-5Li2O-9BaF2 glass fiber is prepared with the rod-tube drawing method of 15 μm core diameter and 125 μm inner cladding diameter applied in the 2.0 μm-infrared laser. The 2.0 μm luminescence properties of the core glass are researched and the fluorescence intensity variation for different Tm3+ doping concentration is systematically analyzed. The...
متن کاملFrequency upconversion emissions in layered lead–germanate–tellurite glasses for three-color display
This letter is aiming to develop a full-color glass for the three-dimensional and three-color display. The Yb/Tm/Er codoped lead–germanate–tellurite bulk glass has been fabricated and the upconversion emissions have been investigated. The reduced blue and green emission intensity suggests that it is difficult to achieve three-color display in the multiple-rare-earth ions doped glass. Then a two...
متن کاملIntense red upconversion emission of Yb/Tm/Ho triply-doped tellurite glasses.
By conventional melting and quenching methods, 3Yb2O3-0.2Tm2O3-xHo2O3 (wt%, x=0.2~1.2) was doped into an easily fiberized tellurite glass with composition of 78TeO2-10ZnO-12Na2O (mol%) to form YTH-TZN78 glasses. Under 976 nm excitation, the direct sensitizing effect of Yb ions (Yb→Ho) and indirect sensitizing and self-depopulating effects of Tm ions (Yb→Tm→Ho) were found to present intense red ...
متن کاملHighly efficient mid-infrared 2 μm emission in Ho/Yb-codoped germanate glass
This work reports the mid-infrared emission properties around 2 μm in Ho/Yb codoped germanate glasses. The glass not only possesses good chemical durability and good thermal stability but also has high midinfrared transmittance around 2 μm (90%). In addition, the glass possesses considerably low OH content (20.45 ppm) and large spontaneous transition probability (103.38 s) corresponding to the ...
