We report on room-temperature continuous-wave laser operation at 2.06 μm in co-doped (0.5 at% Ho, 5.0 at% Tm):KLu(WO4)2 monoclinic crystal pumped at 805 nm by a commercially available AlGaAs diode laser stack. A maximum output power of 93 mW and a slope efficiency of 14.7% with respect to absorbed power were achieved.
