Abstract
Optical properties of BaF<sub>2</sub> single crystals doped with Yb<sup>3+</sup> and Er ions are studied. The highest <italic>ϕ</italic><sub>UC</sub> value of 10.0% was demonstrated for the BaF<sub>2</sub>:Er<sup>3+</sup> (2 mol%) /Yb<sup>3+</sup> (3 mol%) sample under 490 W cm<sup>−2</sup> of 976 nm excitation.
