AbstractRoom-temperature continuous-wave (cw) laser operation is demonstrated with the newly developed Yb:NaLa(WO4)2 disordered crystal by end-pumping with a fiber-coupled diode laser. A maximum output power of 330 mW is obtained with an optical efficiency of 4.9% and a slope efficiency of 6.3% with respect to the incident pump power. The efficiencies in terms of the absorbed pump power are roughly three times higher. Sellmeier dispersion curves for the ordinary and extraordinary refractive indices of the NaLa(WO4)2 host are reported along with crystallographic and spectroscopic properties related to the Yb3+-doping.
