Polycrystalline Yb3 -Er3 -co-doped YAG: fabrication, TEM-EDX characterization, spectroscopic properties and comparison with the single crystals

Popis výsledku v původním jazyce

Yttrium aluminum garnet (YAG)-based ceramics represent a valuable alternative to single crystals as active media in laser devices for specific applications. In this connection, the 1.5-1.65 lm emission channel of Er31-doped YAG is of particular importance for the realization of diode pumped solid state lasers operating in the so-called 'eye-safe' region. A well-known drawback of this material is related to its small absorption cross section in correspondence to the diode pumping radiation at 940-980 nm.However, its emission performance can be significantly improved through sensitization with Yb31 ions that can efficiently absorb the excitation radiation and transfer it to the Er31 ions. This work deals with the fabrication of polycrystalline YAG co-doped with Er31 and Yb31 ions from oxide powders via solid state sintering in high vacuum conditions and its microstructural analysis by transmission electron microscopy-energy-dispersive x-ray spectroscopy to determine the dopants distribu
