The high quality crystals were grown by the Top-Seeded Solution Growth Slow Cooling (TSSG-SC) method with doping levels of 2.5 at. %Tm and 5 at. %Yb. The active media were pumped with a diode laser at 980 nm. We demonstrated the superior performance of KLu(WO4)2 compared to that of KY(WO4) 2 and improved the results already obtained in the literature. The maximum laser output power reached was 157 mW for (Tm,Yb):KLu(WO 4)2 and 123 mW for (Tm,Yb):KY(WO4)2. © 2010 Published by Elsevier Ltd.enghttps://creativecommons.org/licenses/by-nc-nd/3.0/530Diode pumped solid state lasersDouble tungstate crystalsThulium lasersContinuous wave lasersDoping (additives)Pumping (laser)YtterbiumContinuous wavesDiode pumped solid state laserDouble tungstatesHigh quality crystalsLaser generationLaser output powerThulium laserTop seeded solution growthSolid state lasersArticle
