Abstract: The thermo-optic coefficient dn/dT at a wavelength of 1064 nm was measured in a transparent
ceramic yttrium aluminum garnet (YAG) between room temperature and 430 K. The values of dn/dT at
300 K and 400 K were 7.43 × 10‒6 1/K and 10.0 × 10‒6 1/K, respectively. In addition, the dn/dT at
632.8 nm and thermal expansion coefficient were also measured at the same temperature range.
