We report on the first laser emission of (Lu<inf>x</inf> Gd<inf>(1-x)</inf>)<inf>3</inf> Ga<inf>5</inf>O<inf>12</inf> doped with Tm<sup>3+</sup> ions obtaining a slope efficiency of 20% and a maximum output power of 170 mW centered at 2013 nm. Evidences of a multiline emission are shown. Moreover a spectroscopic investigation on six samples of (Lu<inf>x</inf> Gd<inf>(1-x)</inf>)<inf>3</inf> Ga<inf>5</inf>O<inf>12</inf>:Tm<sup>3+</sup> having different Lu concentrations is presented. In particular the stark sublevels energy of <sup>3</sup>H<inf>6</inf> and <sup>3</sup>F<inf>4</inf> manifolds have been determined. Spectroscopic data have been utilized to calculate absorption and emission cross sections and gain curves.
