Thermal expansion coefficients of YAG ceramics doped with Nd³⁺, Yb³⁺, Er³⁺, Sm³⁺, and Cr⁴⁺ ions were evaluated from -150 °C to 700 °C. Measured thermal expansion coefficient of various kinds of YAG ceramics were coincided to Nd:YAG single crystals, and no significant differences depending on dopants were detected.
