Abstract :
2.0μm spectroscopy of a new germanate-tellurite glass with Ho3+/Yb3+ codoping is synthesized and analyzed. Efficient 2.0μm emission of Ho3+ ions sensitized by Yb3+ ions from the host glass is observed under 980nm pumping. The maximum emission cross section of Ho3+ ions transition is 4.32×10-21 cm2 around 2.0μm. The good spectroscopic properties and the efficient energy transfer from Yb3+ to Ho3+ suggest that Ho3+/Yb3+ codoped germanate-tellurite glass may become an attractive host for developing solid state lasers operating in the mid-infrared.
