    Wavefront deformation and thermal stress birefringence were evaluated for high-power TGG ceramic rods. The real laser beam profile used to heat the TGG ceramics was considered in the calculations. The numerical model was bench-marked with experimental data at about 100 W and then used to study the scalability of a similar TGG-based optical isolator up to 1 kW average power.
