Abstract
Laser generation in continuous wave (CW) regime at 1.94-μm from (Tm,Yb) codoped system has been investigated in two different hosts: KLu(WO4)2 and KY (WO4)2. 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(WO4)2 and 123 mW for (Tm,Y b):KY (WO4)2.
