✦ Synopsis

We present continuous-wave laser operation at two wavelengths oscillating simultaneously and originating from two different active ions in a monoclinic co-doped (Ho,Tm):KLu(WO 4 ) 2 crystal. Dual-wavelength lasing is accomplished at room temperature using Ti:Sapphire laser pumping. The Ho-ion, lasing at 2061 nm and the Tm-ion, lasing at 1937 or 1919 nm, generate together a maximum output power of 244 mW with a maximum slope efficiency of 24.8%. Tuning with a birefringent filter is possible from 1854 to 2063 nm, with individual tuning ranges of 1854 to 1980 nm for Tm and 1971 to 2063 nm for Ho.

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. T
