According to recent research published in the Journal of the American Ceramic Society, "Highly transparent Tm:YAG ceramic was fabricated by a solid-state reaction and vacuum sintering. The optical properties, the microstructure, and the laser performance of the Tm:YAG ceramic were investigated."
"A Tm:YAG ceramic with an average grain size of similar to 10 mu m was obtained by sintering at 1750 degrees C for 10 h. The in-line transmittance was 84.0% at 2015 nm. The absorption coefficients at 681 and 785 nm were 8.23 and 3.27 cm(-1), respectively. The grain boundaries were clean and no secondary phase was observed," wrote W.X. Zhang and colleagues.
