Abstract: We report the first laser oscillation on Yb-0.15:(Lu0.5Y0.5)(3)Al-12 ceramics at room temperature. At 1030 nm we measured a maximum output power of 7.3 W with a corresponding slope efficiency of 55.4% by using an output coupler with a transmission of T = 39.2%. The spectroscopic properties are compared with those of the two parent garnets Yb: YAG and Yb: LuAG. To the best of our knowledge these are the first measurements reported in literature achieved with this new host.
