Resumo
We report infrared-to-visible frequency upconversion in Er3+–Yb3+ co-doped TeO2–GeO2–PbO glasses and
fibers. The upconversion is investigated as a function of the co-doping with different Yb3+ concentration.
We observe an increase of the green and red upconversion intensities of up to 400 times with increasing
Yb3+ concentration and explain the mechanism involved in the energy transfer process. The pump source
is a diode laser emitting at 980 nm in resonance with the 2
F7/2 ? 2
F5/2 transition. The tellurite glasses
have a relatively low phonon energy (700 cm1
) among oxides, high refractive index (2), large transmission window (350 nm–6500 nm) and can be easily pulled into fibers. We also characterized fibers
obtained from these compositions and measured similar characteristics when compared to bulk glasses.
