Abstract: We report on continuous-wave lasing at a wavelength of 1030 nm with a maximum power of 80 W and a slope efficiency of 26% in a thin disk element made of domestic ytterbium-doped yttrium–aluminium–garnet ceramics [(Yb_0.05Y_0.95)₃Al₅O₁₂]. The studied ceramic sample was fabricated by solid-phase sintering of a mixture of (Yb_0.05Y_0.95)₂O₃ and Al₂O₃ nanopowders synthesised by laser ablation. The measured laser characteristics in cw and repetitively pulsed regimes are presented.

Keywords: Yb : YAG ceramics, yttrium–aluminium garnet, laser oscillation.
