We demonstrate continuous wave (CW) room temperature laser operation of the monoclinic Ho3+-doped KLu(WO4)2 crystal using a diode-pumped Tm3+:KLu(WO4)2 laser for in-band pumping. The slope efficiency achieved amounts to ~55% with respect to the absorbed power and the maximum output power of 648 mW is generated at 2078 nm.
