Abstract : Thin epilayers of monoclinic KLu(WO4)2 doped with thulium are grown by liquid phase epitaxy on undoped KLu(WO4 )2 substrates. The epitaxial composites are optically characterized and implemented in a cavity, longitudinally pumped (normal to the layer) by a Ti:sapphire laser. Tunable (1894-2039 nm) continuous-wave laser operation is achieved with maximum slope efficiency as high as 64% with respect to the absorbed pump power at 802 nm. The output power is limited by the crystal absorption
