Abstract

<abstract abstract-type="main" xml:lang="en"> <title>Abstract</title> <p>To produce highly transparent Yb‐doped yttrium lanthanum oxide (Yb³⁺:(La_xY_1–x)₂O₃) ceramics two original technologies were used: laser synthesis of nanopowder and pulsed magnetic compacting. Sintering of the compacts in vacuum 3×10^–4 Pa at 1600–1700 °C during 13 hours led to transparent ceramics fabrication. The ceramics with relative density higher than 99.99% and grain size about 40 µm were fabricated. Full transmittance of 1.8 mm thick Yb_{0, 11}La_{0, 23}Y_{1, 66}O₃ ceramics reaches 82.5%@800 nm.
