摘要

We report on the first laser emission of (Lu-x Gd(1-x))(3) Ga5O12 doped with Tm3+ 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-x Gd(1-x))(3) Ga5O12: Tm3+ having different Lu concentrations is presented. In particular the stark sublevels energy of H-3(6) and F-3(4) manifolds have been determined. Spectroscopic data have been utilized to calculate absorption and emission cross sections and gain curves.
