Abstract: 10.1364/OME.4.002274 We studied laser generation of the Ho3+-ion in (Ho,Tm):KLu(WO4)2 crystals pumped by Ti:sapphire and diode lasers achieving output powers up to ~1.2 W. For polarization parallel to the Nm principal axis, the lasers operated at 2078 or 2059-1960 nm depending on the transmission of the output coupler. The maximum slope efficiency with respect to the absorbed power reached ~30% for both types of pump sources. Tuning was studied with Ti:sapphire laser pumping achieving a tuning range of ~180 nm.
