Abstract: Continuous-wave laser action has been demonstrated in a diode-pumped Yb:KYF4 crystal. Crystal growth, spectroscopic measurements, and laser results are presented. A maximum output power of 505 mW, a slope efficiency of 43%, and a continuous wavelength tunability range of 65 mn, from 1013 to 1078 mn, have been obtained at room temperature.
