Název v původním jazyce

A novel IR-transparent Ho3+ :Y2O3-MgO nanocomposite ceramics for potential laser applications

Popis výsledku v původním jazyce

The work is devoted to obtaining of transparent nanocomposite materials as low loss, highly thermally conductive materials for potential laser applications. We report Ho3+:Y2O3-MgO nanocomposite ceramics with excellent mechanical and optical properties by combining glycine-nitrate process and spark plasma sintering. Morphology, structural-phase state, infrared transmittance and luminescence depending on the holmium con-centration (0-12 at.%) were studied for the first time. It was found that optical transmittance reaches 75% @6000 nm for 3 at.% Ho3+:Y2O3-MgO ceramics. The absorption cross-section at 1931 nm and the emission cross-section at 2118 nm were determined to be sigma(abs) = 0.51 x 10(-20) cm(2) and sigma(em) = 0.29 x 10(-20) cm(2), respectively. Based on the testing results of luminescent characteristics it was demonstrated that Ho3+: Y2O3-MgO nanocomposite is a promising material for high-power eye-safe lasers operating in the 2 mu m wavelength range.
