Abstract: Single crystals of solid solutions of a high optical quality are grown in the concentration vicinity of the saddle point of the ternary CaF₂–SrF₂—YbF₃ system. Efficient lasing with a small Stokes shift (at 1025 nm) was obtained in 980-nm diode-pumped single crystals. The total lasing efficiency (with respect to the absorbed average pump power) was 59% and the slope efficiency was 83%.
