Distribution of ytterbium in Yb:YAG crystals and lattice parameters of the crystals

摘要

Yb_(3x)Y_(3(1-x))Al_5O_(12) crystals with different Yb~(3+) concentration have been grown by the Czochralski method. The distribution coefficient of Yb~(3+) is 1.08 +- 0.01, and it has little relation with Yb~(3+) concentration. The lattice parameter of YbAG is 1.193799 +- 0.000054 nm. We have found an equation connecting the lattice parameter and Yb~(3+) concentration: α(x) = 1.200976 - 0.007072x nm.
