We report the first laser operation based on Ho3+-doped LuLiF4 single crystal, which is directly pumped with 1.15-μm laser diode (LD). Based on the numerical model, it is found that the “two-for-one” effect induced by the cross-relaxation plays an important role for the laser efficiency. The maximum continuous wave (CW) output power of 1.4 W is produced with a beam propagation factor of M2 ~2 at the lasing wavelength of 2.066 μm. The slope efficiency of 29% with respect to absorbed power is obtained.
