Yb:CaF2 Crystals, 3%Doping, Right-angle cut

Yb3+:CaF2 is one of the most studied and promising crystals for the development of short-pulse, high-energy, high-power diode-pumped solid-state lasers. The simple structure of this crystal contributes to its good thermal properties. Ytterbium-doped calcium fluoride has a very broad and smooth emission band, which is very special for cubic crystals. We can provide Yb3+:CaF2 crystals with different specifications.
