Two different doping concentrations Nd, Y∶CaF2 crystals (0.6%Nd, 5%Y∶CaF2 and 0.8%Nd, 5%Y∶CaF2, represented by fraction of number of atoms) are obtained by the temperature gradient technique (TGT) method. The absorption and emission spectra, emission lifetimes, laser properties are studied. It is found that codoped Y3+ ions can effectively inhibit the concentration quenching effect and improve the spectral properties of the crystal. The broad and flat emission spectra around 1.06 μm is observed in Nd,Y∶CaF2 crystals, and the emission bandwidths is 26 nm, which is very close to the Nd-glass. While the strongest emission line is at 1054 nm, the fluorescence lifetime, emission cross section, and quantum efficiency of 0.6%Nd, 5%Y∶CaF2 are estimated as 333 μs, 3.6×10-20 cm2, and 76.7%, respectively. The room temperature continuous wave (CW)-laser oscillation is achieved using 0.6%Nd, 5%Y∶CaF2 crystal. The maximum output power is about 413.3 mW, with the slope efficiency of 28.5%.
