To analyze the thermal birefringence effects in laser gain materials, knowledge of the piezooptic coefficients of the materials is required. The piezooptic coefficients of ceramic YAG were measured using the four-point bending method. To our knowledge, this is the first report of this measurement for ceramic YAG. With the measured values, the depolarization of a ceramic YAG laser was analyzed. Overall, the results agree with that of single-crystal YAG in the [111] direction. Ceramic YAG will produce a larger depolarization compared with [100]-direction YAG with an appropriate input polarization angle.
